BrewPiLess can run on [Electrodragon SDPT board](https://www.electrodragon.com/product/wifi-iot-relay-board-spdt-based-esp8266/). It uses ESP-12F, so you can deploy full nodemcuv2. Schematic is [available here](https://www.electrodragon.com/w/ESP_Relay_Board_SPDT).

For flashing, hold down btn2 before plugging in.


| ESP8266 GPIO | NodeMcu Label | Connect to |
| -------------- |:-------------:| :--------------------|
| GPIO5 | D1 | I2C SCL |
| GPIO4 | D2 | I2C SDA |
| GPIO0 | D3 | UP Button (BTN2) or flash |
| GPIO2 | D4 | DOWN Button (BTN1) |
| GPIO14 | D5 | Temperature Sensors * |
| GPIO12 | D6 | Cooling Actuator |
| GPIO13 | D7 | Heating Actuator |
| GPIO15 | D8 | Available |

*IO14 is marked as DHT on the board. It already has 10k pull-up resistor soldered correctly.

When configuring the devices, D6 and D7 should be configured as "Not inverted".
