Pico Wi-Fi HAT (Incomplete Wiki)

Pico Wi-Fi HAT is a compact and easy-to-use Wi-Fi HAT for the Raspberry Pi Pico that includes an ESP8266 module, IEEE 802.11b/g/n Wi-Fi Standard, 3.3 V Operating Voltage, UART Communication interface, and a 40-pin GPIO extension header that can be controlled via AT Command and supports TCP/UDP communication protocol.

Pico Wi-Fi HAT also includes a 1.14-inch display with a resolution of 240 x 135 pixels, 65K RGB colors, and a sharp and vivid exhibiting effect, designed primarily for user engagement via SPI connection by incorporating a GPIO header. The 1.14-inch LCD includes the ST7789 Driver and SPI Interface, decreasing the amount of IO pins required.

It's a simple way to enable Wi-Fi on the Raspberry Pi Pico, making it suitable for a variety of IoT communication projects. It is intended for developers of all skill levels, from the most experienced to those who are just getting started with IoT devices.

Installation

MicroPython

All Pico Wi-Fi HAT comes with preloaded AT firmware, So you can develop and design your projects without updating AT firmware for ESp8266.

TCP Server
  • Stack Pico Wi-Fi HAT with Raspberry Pi Pico.
  • Now Run Hercules Setup Utility (Download link is available under the Resources section below) and select tab TCP Server, enter port number as 8080 (you can choose any other port as well) and finally click on Listen button to start the TCP server on your PC/Laptop. Note down your PC/Laptop IP address to access your TCP Server.

  • Make sure to connect your PC/Laptop and Pico Wi-Fi HAT on same router. For example: If your Wi-Fi SSID is "TEST" and password is "test1234", then you must connect both device on TEST network.
  • Now open Wi-Fi_TCP_Client.py in thonny ide (You can find code here : https://github.com/sbcshop/Pico-WiFi-HAT ), Don't forget to change SSID, Password and TCP server IP (Laptop/PC IP on which TCP server is running), Run this file by clicking on green play button. It will make connection with TCP_Server and sent hello message, you can also sent back any message from server to WiFi HAT.
