What it is?

Arduino compatible board with ATmega 328P at 16MHz@3.3V.

Size 5 x 5 cm.
RFM69W/HW option with IPX connector on back.
OneWire header for iButton devices and 2 LEDs.
Piezo buzzer on RS485 boards.
IO header

Power options are:

DC 5-20V with fuse and polarity protection.
Li-Ion Li-Po battery 3.7. There is voltage divider at ADC7 with ratio 2:1. Optional micro USB charging.

Communication options are:

RS485 for serial over twisted wire pair, with terminator pins and termination resistor.
RFM69W-868 for wireless standard range.
RFM69HW-868 for wireless long reach.

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.

Why did you make it?

It is node that can be easily connected by wire or wireless to OHS gateway.

What makes it special?

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.
