Description: 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.
