Realy nodes

After some testing I have finished new relay node. As all nodes it is Arduino compatible board with ATmega 328P clocked at 16MHz@3.3V.

Size 6.1 x 5.6 cm.
On-board AC/DC power supply. Input 100-240VAC, 50-60Hz. Output 5V/3. Fused with TVS on input with slow blow 0.5A fuse.
2x Japanese(Panasonic) power relays with COM, NC and NO inputs. With TVS on both.
It has more powerful RFM69HW soldered on back with IPX connector.
Temperature sensor to indicate overheating based on MCP7900A on ADC6. It is mounted under AC/DC power supply.
IO header, rest of pins are taken out. As well as +5V and +3V3 to add another relays or sensors.
Programmable via standard FTDI 6 pin 3V3 programmer.

It is available in my online store. Schematic is in my shared folder, and example sketch is placed on GitHub.
