ESP8266 WiFi Module for Raspberry Pi Pico

This is a WiFi expansion module designed specifically for the Raspberry Pi Pico, giving your Pico WiFi functionality for your projects - great for Pico IoT projects!

The module can be controlled via UART AT command and supports the TCP/UDP communication protocol. The board comes pre-soldered with dedicated female headers for your Raspberry Pi Pico. A reset and boot button are included onboard for the ESP8266 module, alongside a power indication LED.

Note: Raspberry Pi Pico not included. You'll need a Pico with male headers soldered to it. You can grab a Pico here and Pico male headers here, or buy a Pico with pre-soldered headers.
