About the Normalpad PCB

Normalpad is an open source RP2040/RP2350 PCB design by nathantsai1, published on GitHub. It is a 2-layer board measuring 335 × 132.7 mm, with 165 components from 9 distinct parts.

Its main chip is the Pico, from the RP2040/RP2350 family. By type, the board carries 82 switches, 82 diodes and 1 IC.

It belongs with the keyboards designs in this gallery.

From the project

*Note: this is a hackboard, not a hackpad ## What is this? This is a 75% keyboard inspired by the Keychron Q1 Custom Keyboard. It consists of 82 keys, hot-swappable switches a 3D printable case, and stabilizers. The bottom half is split in half to make it easier to sand

*The more important files are contained in the production folder, README, and bom(in a ccsv file and at the end of this page) ## Why did I make this I primarily started this for HackPad v2. However, during the process of making this, I learned more about the different types of switches, stabilizers, splitting up CAD designs…

Normalpad: common questions

What microcontroller does the Normalpad use?

The Normalpad is built around the Pico, from the RP2040/RP2350 family.

How big is the Normalpad PCB?

The Normalpad measures 335 × 132.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Normalpad?

165 components, from 9 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Normalpad design files?

From the nathantsai1/normalpad repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Normalpad design in my own project?

The repository has no license, so all rights stay with nathantsai1. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Normalpad 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.
