2 Layer Board - 1.1624 sq in (1.3300in x 0.8740in) / 749.93 sq/mm (33.78mm x 22.2mm)
$4.65 per set of 4 ($4.00 per sq in)
MySensors Node RS485
ATmega328 + MAX485 + W25X40 flash for FOTA
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 510 Ohm resistor.
