Hello
I'm in doubt if I need a VE.Direct-USB cable or can I assemble a serial cable?
I want to connect my smart solar MPPT 100/15 and 75/15 either to an Arduino with serial or maybe to en Rasp.Pi to get data logging.
I've read about galvanic problems to connect directly...
Any hints, solutions to create serial or usb cable?
28u$ is a lot of money for people living in Argentina :-(
