Just a quick update on progress that I’m making behind the scenes. The below board is a prototype design for a new controller module using the ESP32.
The board has hardware for:
- Two mechanical relays (5A, 60V)
- One 0.5A, 60V SSR relay (on board)
- An ATTINY/Arduino ISP programming header (so the controller can program the modules without needing PlatformIO or a computer/USBASP interface)
- RS485
- CANBUS
- Four additional I/O pins
- Two connectors for connecting the existing modules to
- A colour TFT screen supporting SD CARD and Touch - although this is optional as most people won’t need it.
- An RGB LED for status
The board is physically larger 122mm x 87mm but is designed to fit inside a DIN rail enclosure, like this one.
There are no release dates or files available for this at the moment, and no code has been written to support the new features - but I’ve ordered some prototype PCBs to begin all that.
