60 keys keyboard variants

This repository contains everything to build different variants of my 60 keys keyboard layout. The layout is designed with 10 finger typing, programmers & gamers in mind.

The following variants are available at the moment:

- simplyKeeb S60ph - A completely 3D printed hotswap split keyboard - simplyKeeb S60 - A pcb variant of the S60ph using a RP2040 and smd components

SimplyKeeb-60K: common questions

What microcontroller does the SimplyKeeb-60K use?

The SimplyKeeb-60K is built around the C2040, from the RP2040/RP2350 family.

How big is the SimplyKeeb-60K PCB?

The SimplyKeeb-60K measures 291 × 153.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SimplyKeeb-60K?

158 components, from 20 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 SimplyKeeb-60K design files?

From the geaz/simplyKeeb-60K 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 SimplyKeeb-60K design in my own project?

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

Can I test firmware for the SimplyKeeb-60K 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.
