More info


Wi-Fi module based on the ESP8266 system - simplicity of use (communication through UART, supports AT commands), 3.3V power supply, support for WPA / WPA2 encryption - these features make the EPS8266 module applicable to nearly everywhere, where reliable and effective data transmission is needed. The module contains an integrated microstrip antenna, thanks to which the dimensions of the module allow you to save space while maintaining functionality. The communication connector is a double-row goldpin, thanks to which it is possible to place the module for e.g on a contact board or connect cables with an Arduino board whose interfaces are supplied with 3.3V voltage.

The module operates in the 802.11 b / g / n standard (2.4 GHz).
