ESP32 3-Button LED Learning Board Bare PCB

Description

ESP32 3-Button LED Learning Board Bare PCB

Two-layer through-hole learning board by Siddhi Patel with footprints for three buttons, three LEDs and socket headers for a removable ESP32 development board.

Applications

Beginner soldering, GPIO input/output exercises and custom memory-game development.

What you receive

One unpopulated carrier PCB. ESP32 development board, LEDs, resistors, buttons, headers and cables are excluded. Check the development board pinout and header spacing before assembly. The upstream project provides hardware-test firmware; final memory-game firmware is still planned. This is a learning platform, not a complete playable game.

DIYIPCB independently manufactures this open hardware design. It is not an official product of, or endorsed by, the original designer. Images are bare-board CAD previews, not photographs of stocked assemblies. Actual soldermask and surface finish may differ.
