Waveshare ESP8266 for Raspberry Pi Pico Wifi Module TCP UDP

Waveshare ESP8266 for Raspberry Pi Pico Wifi Module TCP UDP is a WiFi expansion module for Raspberry Pi Pico designed for wireless IoT communication, TCP/UDP networking, UART AT-command control, remote data upload, and Pico-based embedded connectivity projects. It is built around an ESP8266 module and gives Raspberry Pi Pico boards a simple way to add WiFi networking without requiring a separate custom radio design.

The Pico-ESP8266 communicates through UART and uses standard AT commands, which makes it easy to integrate into both C/C++ and MicroPython projects. It supports WiFi STA, WiFi AP, and WiFi STA+AP modes, together with the built-in LWIP protocol stack for TCP and UDP communication, making it a practical wireless add-on for Raspberry Pi Pico applications.

Other Content

Why this module matters
This module is useful because it gives the Raspberry Pi Pico a practical WiFi path through a familiar UART + AT command workflow. That makes it much easier to enable wireless networking for prototypes without needing to build a full custom ESP32-based redesign.

Development advantage
Because it supports both C/C++ and MicroPython examples, it is suitable for both quick learning projects and more advanced embedded communication development.

Onboard controls
The board includes two functional buttons so users can update AT firmware and control the ESP8266 module more easily during development and testing.
