First draft of a ECU Main Board. This one is 120mm long to fill the box with only Power and Ethernet connector – or well I left the USB on this draft. The only connectors are 8 module connectors and 2 links. The PSU is as before, PSRAM and SPI Flash the same as before, Ethernet uses a trafo and M12-4. Power is actually M12-2 – it is just that the 3D package is M12-4. Only 4 Leds this time.
The Main board is a bit empty since all IO now is on modules – I could have made the PCB smaller, but the size is decided by the box – that said it is tempting to attempt a smaller PCB as I look at the wastland above – lets see – I have a few more things to add.
