Does Your Microcontroller Work? - Tiny GPIO Testing PCB!

In this video, I walk through a custom PCB project designed in KiCad to test GPIO functionality on microcontroller boards like the RP2040 and Arduino. The board uses 30 0603 LEDs—15 for logic HIGH and 15 for logic LOW—to visually verify pin behavior. I explain the design process, solder the board, and test it with a microcontroller.
