Victron Raspi HAT

Hi All

Progress on the the Raspi HAT code name is called the Stetson as it does not follow the Raspi HAT

protocols, so i named it the Stetson due to space constraints in the PCB design with all the relays and plugs and sockets required etc.

It has the following inputs and outputs canbus PSU etc. All has being tested and confirmed working OK to date. as of version on Venus Ver 2.60. release and 2.66 candidate. All OK, For Later Version >2.66 there are issues that not all works as it used to. Update some progress with new version >2.66 to 2.80.19

As in Bold all working again except the VE direct I2C ports USB is OK.

2x Temperature using the the LM335 devices: Working OK on Ver 2.80.24 Added 4 temps

3x Tanks resistive: Working OK on Ver 2.80.24 Added 4 tanks

5x Digital Hi ports all isolated with pulse counting etc: Working OK on Ver 2.80.24

1x Canbus port Working: OK on Ver 2.80.24 on USB and SPI ports

2x VE Direct ports: Not sorted yet with software USB OK but

6x relays outputs: Working OK on Ver 2.80.24

1x PSU from 10 to 55vDC to be upgraded to higher voltage 75vDC

Attached schematic for you information.

Options for the future: buzzer indicator, code is there just need some time to redirect the code to the right GPIO pins to make it work.

The PCB design is almost complete, it will mount in a din rail enclosure and a main 40 pin ribbon cable will connect between the Raspi and the Stetson. Updated PCB files with VE direct ports.

Update 20/10/2021 Schematic updated to full 6x relays on board and new PSU module and the 4x Tank and 4x Temp sensor inputs. Digital input circuit change, PCB is done, BOM done.

Hello,

I've searched this forum thoroughly, looking for upgrades on my raspberry pi venusos installation. This raspberry pi HAT seems awesome. I've already contacted Rob Duthie

He told me there are some people making these awesome boards? Is there a way to buy a board somewhere? Would like so very much!

Thanks in advance,

Hi Jimmy, did you ever get the information? I am in the same situation and have got some temp sensors working on my pi4. I really like the look of the all in one hat by Rob. Do you know if these are available for purchase?

Rob Duthie jondrane commented · May 07 at 09:36 PM

Yes all the temp and fuel sensor all work OK 4x4 of each, if i had more time i woild do the PCB etc, there other out there how are making them based on my design.

If and when in get a chance i would make them i had a complete Din rail case to mount them into from aliexpress etc.

Regards

Looks awesome. Can I make some suggestions?

- 2 x CAN, isolated, like the Octo-GX, using RJ-45 connectors, or a board-mounted dip for termination resistor

- Ideally a whole other isolated CAN that can be a different speed (for can-bms and can-xxx at the same time)

- ve-direct ports that dont peel off the board when you look at them wrong like the ones on Octo-GX

- PSU with a +12V output as well for integration w/ the relays

- smd LEDs on the board at each input / relay output to show state

- if you can put all connections on one edge, otherwise it doubles the size of the install

- don't use spring connectors, use screw types and oversize them

Hi Vincent

Answers in bold

- 2 x CAN, isolated, like the Octo-GX, using RJ-45 connectors, or a board-mounted dip for termination resistor. I will look into a dual isolated depends if another interrupt is required or not. I have already a 120 ohm jumper on board. I am using hard wired screw header connector

- Ideally a whole other isolated CAN that can be a different speed (for can-bms and can-xxx at the same time) as above, i have testing the canbus with a pylon US2000 with the USB port and direct canbus port both work OK, it will need some extra code to add the can0 and can1 ports? so far it is bullet proof with just can0 running.

- ve-direct ports that dont peel off the board when you look at them wrong like the ones on Octo-GX:Only have one serial port to work with for the VE direct port i will add a isolated serial port to suit RJ45 connector OK or screw terminal?

- PSU with a +12V output as well for integration w/ the relays: Can be added means another DC to DC converter PSU has to added to what current are you looking at 1Amp?

- smd LEDs on the board at each input / relay output to show state: Yes i was thinking about that and now will add into the design.

- if you can put all connections on one edge, otherwise it doubles the size of the install: I have used a dual edge Din rail enclosure to keep the PCB small, enclosure 125x90mm. other wise i will have to use a lot longer enclosure, due the size on the connectors i am using, i could use micro connectors, but is tight for the larger wires sizes there are trade offs.

- don't use spring connectors, use screw types and oversize them: I have used plug and header socket with spring terminals as standard. which take the larger wire sizes. These are duel in line to save space for the Analog and DIO ports the relays are screw terminal header plugs.

Vincent Royer Rob Duthie commented · Jan 10, 2020 at 12:59 AM

For Ve-direct maybe the best way is to implement direct serial input, its 5V ttl iirc, so you'll have to level shift it. But I wouldn't omit it entirely from your design.

For the 12V out, you don't need a lot of current, 1A is fine, but something with built in flyback so we can hook it up to a bigger contactor. Some designs offer the ability to switch the relay COM to a 12V source (I prefer a separate output). Can use it to drive a bigger status LED or even a small fan.

For the terminals, I've never used a spring terminal I didn't wish was a screw terminal instead. There just doesn't seem to be a situation where they are better.

Are you using one of those little white Din-rail RPi cases by phoenix contact?

Rob Duthie Vincent Royer commented · Jan 10, 2020 at 02:15 AM

Why screw connectors for CAN? you should stay with the Victron standard of RJ45. It eliminates user headaches figuring out their own can cables. Also, when you connect it to Victron equipment, you will have to cut an RJ45, leaving you with tiny 26AWG wires which won't reliably connect to your screw terminals.Use RJ45! I use boot laces with no problems There are other applications for other lithium BMS battery connections that don't use RG45 connectors i will consider it. Have to consider BYD and Pylontech and other manufactures as well plus the other DIY user of Tesla and Nissan leaf batteries etc.

For Ve-direct maybe the best way is to implement direct serial input, its 5V ttl iirc, so you'll have to level shift it. But I wouldn't omit it entirely from your design. : Done, levels shifted and isolated. Needs to be tested i am using pins 8,10 on the the raspi GPIO which are the UART.

For the terminals, I've never used a spring terminal I didn't wish was a screw terminal instead. There just doesn't seem to be a situation where they are better. Had no issue to date with spring terminals, they are used only on the Analog and digital inputs, due to space constraints etc.

Are you using one of those little white Din-rail RPi cases by phoenix contact?

No, too expensive i am using a Chinese version with a tinted grey clear top Note: With the changes required the design of the PCB has blown out. So will have to upgrade the enclosure to the next size up. 150x90mm.

Looks awesome! Im keen to build one of these up. @Rob Duthie have you had PCB's built? Do you plan on selling a kit or sharing the greber files? JLBPCB have a build service ive used in the past, not sure if they will have the chips in your design tho.

Yes i will be sharing, and selling the main PCB and din rail mounted enclosure all the parts are common nothing odd ball.

Just finalization of the PCB design.

I use Altium for PCB work, so i work in pcbdoc file format.

do you know the answer to my separate thread about getting dbus-adc directory for the Rpi I have a card with the chip on ( and driver I think) but need this directory to get Venus os to recognise it.

Thanks

Rob Duthie laurenceh commented · Jan 26, 2020 at 11:26 PM

Hi Laurence

Have you installed the updated file dbus-adc into /opt/victronenergy folder

Then runs these commands to activate, this is all that is required to make the ADC to work.

install dbus-adc file into /opt/victronenergy/ // (install via Bitvise the file ( dbus-adc )
chmod 755 /opt/victronenergy/dbus-adc/start-adc.sh
chmod 755 /opt/victronenergy/dbus-adc/dbus-adc
chmod 755 /opt/victronenergy/dbus-adc/service/run
chmod 755 /opt/victronenergy/dbus-adc/log/run (need to add a folder called log and a file called run inside it) if missing?
touch /var/log/dbus-adc (sets time stamp of the file or created one)
ln -s /opt/victronenergy/dbus-adc/service /service/dbus-adc

I know I need to do these things what is puzzling me is where to find the dbus-adc files required, so explicitly :

What do I download from where?
if they are part of larger image how do I extract the files required?

Hi Rob,

May I suggest not using SI8422 plus MCP2551? They are not so reliable parts in ICS environment. Instead please use ISO1050 from TI

0 ·

Rob Duthie mihair commented · Jan 28, 2020 at 06:27 AM

The ICS stands for industry control systems? more robust device.

What is wrong with the MCP2551 device? this is what i have used and have no problems to date connecting to a Pylon tech BMS systems etc.

So you saying to use just the one combined chip with isolation and canbus, which would make sense and one less part to wire up etc.

OK i will take your advise, re do the schematics and PCB, and up load later.

Regards

Rob D

0 ·

mihair Rob Duthie commented · Jan 28, 2020 at 06:42 AM

Nothing's wrong with MCP2551 itself but your implementation has the can converter as last device on the bus, after the isolator. In case of voltage spikes it could be easily damaged or communication perturbed

From the ISO1050 doc:

As a CAN transceiver, the device provides differential

transmit capability to the bus and differential receive

capability to a CAN controller at signaling rates up to

1 megabit per second (Mbps). The device is designed

for operation in especially harsh environments, and it

features cross-wire, overvoltage and loss of ground

protection from –27 V to 40 V and overtemperature

shutdown, as well as –12-V to 12-V common-mode

range

Hi All

Just an update on the stetson, we could have up to 6 output relays if required (Mark UK) has tested it to 8 but some GPIO clashed with the canbus control, but i need to confirm as i am running out of space to to fit them all, unless i upgrade the PCB design and case i had in mind to use, as the case was a din rail mount type with a cover 150x90x45 etc.

As per photo attached.

OK updated PCB and Schematic to have 2x extra relays they are named Aux 1 & 2 as they control a 12v external relay coil only, due space constants etc. They have a indicator LED each and an output current of 500mA max.

Confirmed we have 6x relay outputs all working OK now. An you can name as required via WinSCP. If some one wants the files just email me and i will send the required files to make the 6 relays work, just a matter of copy and paste into the Venus folders.

Very nice initiative! I assume te RPI is powered via the Stetson board, I know on RPI there is a fuse to protect against overvoltage etc. located at the micro USB connector on the RPI, powering over the RPI header bypasses this fuse. Would this be useful to add a fuse on the stetson on the 5v pin that powers the RPI?

Oh, and what about gps? Is it possible to add another hat fo GPS or would USB GPS be the only option?

Cheers,

Menno

Rob Duthie captain-nemo commented · Jun 02, 2020 at 12:16 AM

Hi Captain Nemo

Thanks for the feed back, looking at extra power protection etc. I do have over voltage protection built in, and a USB port which can be feed to the raspi directly etc. As the unit has dc to dc power regulators converters, external fusing is required as like the CCGX units have done.

Also there is a 12v 1amp feed output for the external relays coils etc.

The GPS works already by plugging in a USB GPS receiver type # BU-353S4 and these work very well with no issues to date.

Updated files below.

Hi rob,

Thanks for the feedback!
what would be the next step to make this board? Is it ready to use or does it need more testing? If it needs testing, can I help? For pcb making a gerber file would do, but soldering Smd it not my strongest suit. I know some local pcb companies that I used for making pcb’s for my company. Silk screen etc are also needed in this case.

Please advice on what I can do.

Rob Duthie captain-nemo commented · Jun 02, 2020 at 10:39 PM

The PCB you can make your self if required once i release the Gerber files etc.

Hand soldering will be slow and time consuming etc. The PCB will have all the silk screens in place etc.

So just going threw final checks and BOM etc now.

Yes Rob's is far more advanced than the one I made with robs help.

As you will see there is a lot of work goes into this and Rob has put a lot of time and effort into it. And then gives the plans free of charge to people.

The unit on MBC website is for people who don't want to make it or spend the time making it from components.

The cost is for making it and supplying it as a plug and play unit.

I'm sure you will see what goes into now you have the plans to make one.

I know this is very late in the game but I was wondering if it would be possible to provide the option of converting the tank sensor inputs to temperature sensor inputs. It appears the only electrical difference is the pull-up resistor on the input. Through hole parts would be easier to change out, or maybe you could provide a jumper to select the correct pull-up.

I have a SeeLevel tank system so there's no need for the tank inputs but can see using at least 4 inputs for temperature sensors around the RV: inside/outside temps, refrigerator/freezer.

I followed the story and all the progress you made so far.
Raspi, Venus and Victron components are ready for my camper van.
Currently running venus 2.66.
There are many approaches to connect and controle devices of any kind. But your Victron Raspi Hat appears to be the right choice to cover (almost) all needs.
It will definitely ease my life.

Therefore I would like to kindly ask for the latest pcb- and BOM-files.

Dear Rob Duthie, i've been following a lot of your posts and you are doing great work for this community, can i ask if you can send me this PCB with the SMD parts already soldered?
I have no problem paying for the work, soldered parts and shipping.
I will solder the THT parts myself as they could increase the chance of damage in shipping
You can reach me through email at dennispochenk@gmail.com and i can do Paypal of Bank transfer.

And maybe one note on what could be improved: The mounting holes for a shielded RJ45 bus connected to ground are missing, adding the posibility of using a shielded cable would lower the chance of interference with devices along the CAN cable and would always be optional.

was there any update lately? Did you test the HAT with Venus os v3.0?

Is it possible to buy whole product or pcb/parts?

Are these available for purchase? I have read through this topic, but admittedly this form of communication is horrible at best. Comments are scattered throughout with no clear timeline that is discernible.

I’m interested in a finished product, if available.
