More info


The development board allows for integration with Wi-Fi module (ESP8266) which is known for its simplicity and considerable capabilities with overlays (shields) with a spacing of connectors compatible with Arduino UNO R3 giving a lot of opportunities for the development of the IoT project. The board is compatible with WeMos D1 and NodeMCU.

The maximum allowed voltage on the lines of the ESP8266 system is 3.3 V. Make sure that the additional module attached to the board does not force the lines of the ESP8266 voltage higher than allowed.
