Arduino compatible board with ATmega 328P at 16MHz@3.3V.
Power options are:
Communication options are:
Possibility to add thermometer based on MCP7900A on ADC6.
Programmable via standard FTDI programmer. RS485 version is programmable only via ISP(6-pin) as hardware serial is connected to RS485 chip, use upload via programmer in Arduino IDE.
Just to ones that are curious what are the missing components. This board can be either battery or DC powered, and also can communicate over radio(RFM69HW) or RS485.
It is node that can be easily connected by wire or wireless to OHS gateway.
Let's say it is just another Arduino clone, but equipped to have all peripherals you need to create authentication node for OHS gateway. Or simply any sensor connected to OHS.
