On Danyboard M0 is mounted a wifi module ESP-WROOM-02 with FCC and CE certification. It is a low-power 32-bit MCU Wi-Fi module based on ESP8266 chip.
The wifi module interacts with the microcontroller via a UART (hardware serial ports).
You can control the wifi module via the classics AT commands, typically used with ESP8266, or by using a library.
On this page I will show you how to use the WiFi module through WiFiEsp library.
