My neat hw implementation with M5stack ATOMIC CANBus Base

[arzaman]

Hello again @Sleeper85 , thank you for your ongoing contribution to keeping the original source code open!

I'd like to share a neat and simple hardware alternative for implementing the protocol converter.

I utilized components from M5stack:

ATOM Lite, an ESP32 pico controller
ATOMIC CANBus Base

By simply connecting the 'grove' port to the JK-BMS TTL GPS port with a straightforward JST cable adapter and routing the CAN output to the Deye sun-5k-sg03lp1-eu inverter, everything functions seamlessly, as demonstrated.
The power supply is currently temporary from the USB-C Atom port.

My next steps involve integrating a DC-DC step-down converter to power the circuit (and possibly my Rpi running home assistant) from Vbat. Additionally, I plan on incorporating an OLED display to visualize real-time relevant parameters like State of Charge (SoC) and voltage.

I'll reach out via private message to discuss potential contributions further to keep the project open soruce sw and open source hw
