Overview The Pico Expansion LED is a practical Pi Pico expansion board that brings together GPIO status LEDs, a reset button for Raspberry Pi Pico and dual 2×20-pin headers in one compact PCB. It is designed to make day-to-day development, debugging, teaching and prototyping with Pi Pico much more intuitive and convenient. At its core, this Pico Expansion LED board provides IO status indicator LEDs for each GPIO pin. When you run code, toggle outputs or read inputs, the corresponding GPIO status LEDs change in real time, giving instant visual feedback.
This is especially helpful for beginners learning digital logic, as well as for makers who want to quickly verify GPIO state without connecting extra test equipment. The board also adds the missing reset button that many users want on their Pi Pico. Instead of repeatedly unplugging and re-plugging the USB cable, you can tap the onboard reset key on the Pico expansion reset board to restart the microcontroller during firmware development, MicroPython experiments or C/C++ projects. Two sets of 2×20 stackable pin headers turn this product into a very flexible Pico GPIO expansion board.
You can easily plug in other Pico expansion modules, attach Dupont wires to breadboards, or mount the board inside an enclosure while keeping full access to every pin. Clear pin-function silkscreen on the PCB helps you locate each signal quickly during wiring. Powered by 5 V supplied through the Pico itself, the Pico Expansion LED keeps the design simple and compact. With its power indicator LED, M 2.5 mounting holes and moderate dimensions ( 105.8 × 58.1 mm), this Pico Expansion LED GPIO status & reset board is well suited for electronics teaching, lab benches, maker projects and any setup that needs a clean, visual Pi Pico expansion board without extra complexity.
