The Pico-ESP8266 is a WiFi expansion module designed for Raspberry Pi Pico, which can be controlled via UART AT command, and supports TCP/UDP communication protocol. It is an easy solution to enable WiFi feature for Raspberry Pi Pico, suitable for sorts of IoT communication projects.

• Standard Raspberry Pi Pico header, supports Raspberry Pi Pico series
• UART communication, controlled via AT command, helps you get started quickly
• Supports STA, AP, and STA+AP three WiFi operating modes, embedded LWIP protocol stack, supports TCP/UDP communication
• Based on ESP8266 module, four-layers process, enhanced impedance matching, stronger signal, more stable connection
• 2x functional buttons, convenient for user to update AT firmware through Raspberry Pi Pico
• Comes with development resources and manual (Raspberry Pi Pico C/C++ and MicroPython examples)
