This project uses a custom designed RPi hat containing four channels of current/voltage monitoring (using INA209) and temperature sensing (using 1-wire sensors). This is intended to provide telemetry for my camper van electrical system monitoring, charging/discharging and battery/electronics temperature and state of charge
Status (12/03/2016): Fabricated board has been received. Smoke test passed. Now testing I2C interfaces.
Great!!!!
