Repo with my PCB designs and keyboard firmware

This repository contains the source files for keyboard designs and keyboard firmware.

Plotted gerber files can be found under the GitHub repository's releases.

Assembled PCBs for selected designs are available on the RGoulter's Keyboard Labs store.

- PCB smaller than 100x100 mm2, so that it's cheaper to fabricate at various PCB fabricators. - Reversible PCB (use the same PCB for left/right halves). - Using the WeAct Studio MiniF4 "black pill" dev board, a cheap STM32F4 dev board that runs ARM. - Low profile (PCB + choc switches + bumpons). - Column-staggered arrangement of key switches. -…

CH32X-60-ANSI-Improved: common questions

What microcontroller does the CH32X-60-ANSI-Improved use?

The CH32X-60-ANSI-Improved is built around the CH32X035C8T6, from the WCH CH32/CH55x family.

How big is the CH32X-60-ANSI-Improved PCB?

The CH32X-60-ANSI-Improved measures 285 × 94.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the CH32X-60-ANSI-Improved?

149 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the CH32X-60-ANSI-Improved design files?

From the rgoulter/keyboard-labs repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the CH32X-60-ANSI-Improved design in my own project?

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

Can I test firmware for the CH32X-60-ANSI-Improved without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug WCH CH32/CH55x firmware against it before you order a PCB.
