$4.65 per set of 4 ($4.00 per sq in)

MySensors Node RS485
ATmega328 + MAX485

D7 pin used for control RS485 DE/RE input.

On long side of board present 11-pin header include:

D2, D3, D4, D5
A0, A1, A4/SDA, A5/SCL
GND, 5V

On short side of board present two pin header include:

5V, GND, D2, D3 (for simple connect sensors like DS18B20, DHT22)
RES, TX, RX (for connect UART)

Present place to solder pull-up resistors for RES, D2, D3, SDA, SCL signals.
It is also possible to install LED connected between D6 pin and 5V through 510Ohm resistor.
