About the Minikeyboard PCB

Minikeyboard is an open source RP2040/RP2350 PCB design by zelmotas, published on GitHub. It is a 2-layer board measuring 44.5 × 64.9 mm, with 7 components from 3 distinct parts.

Its main chip is the XIAO-RP2040-DIP, from the RP2040/RP2350 family. By type, the board carries 4 switches, 2 diodes and 1 IC.

It belongs with the keyboards designs in this gallery.

From the project

This repository contains the complete design, documentation, and firmware for my hackpad project. Everything needed to understand, modify, or build the device is included through structured folders and clear visuals.

This repository is divided into three main folders for clarity and ease of navigation:

Contains a single file representing the entire hackpad assembly. Accepted formats: .STEP, .STP, .3MF. * Should include the PCB model (a rectangular placeholder is acceptable) and all case parts.

Minikeyboard: common questions

What microcontroller does the Minikeyboard use?

The Minikeyboard is built around the XIAO-RP2040-DIP, from the RP2040/RP2350 family.

How big is the Minikeyboard PCB?

The Minikeyboard measures 44.5 × 64.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Minikeyboard?

7 components, from 3 distinct parts. The full bill of materials is listed on this page.

Where can I download the Minikeyboard design files?

From the zelmotas/minikeyboard repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Minikeyboard design in my own project?

The repository has no license, so all rights stay with zelmotas. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Minikeyboard 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.
