A compact, customizable keypad with programmable buttons that automate complex commands or shortcuts with a single press.(this project need continue to build)

These are the CAD models designed in Fusion 360.

This macropad uses QMK firmware for mapping the 8 keys. You can customize them for playing music, videos, or other shortcuts.

Micropad-2x4-v1: common questions

What microcontroller does the Micropad-2x4-v1 use?

The Micropad-2x4-v1 is built around the XIAO-RP2040-DIP, from the RP2040/RP2350 family.

How big is the Micropad-2x4-v1 PCB?

The Micropad-2x4-v1 measures 95 × 66.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Micropad-2x4-v1?

21 components, from 5 distinct parts. The full bill of materials is listed on this page.

Where can I download the Micropad-2x4-v1 design files?

From the Hanifz99/Micropad-2x4-v1 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Micropad-2x4-v1 design in my own project?

Yes, under the terms of its GPL-3.0 license, which Hanifz99 chose for the repository.

Can I test firmware for the Micropad-2x4-v1 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
