Product description: ESP8266 WiFi Module for Raspberry Pi Pico - Waveshare 20182
A module in the form of an overlay to Raspberry Pi Pico Waveshare 20182 overlay module which extends its functionality with WiFi communication. Produced by Waveshare module, it is equipped with ESP8266 chip, which allows WiFi communication with support for TCP / UDP protocol. On the board there are also two buttons and LED indicating operation status.
The manufacturer has prepared a user guide with sample programs for Raspberry Pi Pico.
Overlay for Raspberry Pi Pico with ESP8266 WiFi module.Main features of the Pico WiFi overlay
- Standard Raspberry Pi Pico pins for plugging the module into the board.
- Communication via UART interface, controlled by AT commands.
- Supports three WiFi modes: STA, AP and STA+AP, built-in LWIP protocol and TCP / UDP communication.
- Based on ESP8266 module, four-layer process, improved impedance matching, stronger signal and more stable connection.
- 2 user buttons, convenient for Raspberry Pi Pico to update AT software.
- Programming resources and instructions for Raspberry Pi Pico in C/C++ and MicroPython have been prepared.
