Excellent board that can be used with MicroPython and Circuit Python. I have used it with a WIZnet WIZPoE-P1 PoE Module and 1.3" OLED Display Module for Raspberry Pi Pico / 1.8" LCD Display for Raspberry Pi Pico and epaper hat. I used it to create an Network port tester. I have also created with these and an AHT20 a temperature logger that sends to a Python program to host a website and also store data to CSV. These combination of boards create numerous posibilities.
