Bill of materials
This page lists all elements required to build MqGateway device on the PCB. PCB is prepared to work with one of the SOC:
- Nano PI NEO,
- Raspberry Pi 3 or 4.
Theoretically software should work on both, with simple configuration change, but it has not been tested on Raspberry Pi. That is why currently it is advised to use NanoPi NEO.
