More info


The development board allows you to integrate Wi-Fi module (ESP8266), known for its simplicity of use and considerable capabilities in projects requiring network access, eg within IoT. The module has 11 digital I / O pins with interrupt, PWM, I2C and 1-Wire. There is also one analog input (input 3.2 V max). The module is programmed through the Micro USB connector. The board is compatible with Arduino , MicroPython 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.
