Description

CH32X-48: Low-Budget PCBA in BM40/JJ40 Form-Factor

A very simple 48-key PCBA which uses the CH32X MCU.

The keyboard uses rgoulter's smart-keymap firmware, which uses the sophisticated and modern Nickel configuration language to declare keyboard and keymap definitions.

The CH32X MCU uses RISC-V, and supports writing firmware with Rust.

Design goals:

• PCBA, using the powerful RISC-V CH32X0 MCU.

• Low Budget.

• Same mounting holes as JJ40/BM40/PyKey40.

• Firmware: See https://github.com/rgoulter/smart-keymap

A bottom plate can be used to protect the components underneath the PCB.

Source files for plates to cut (or cases to 3D print) can be found under cad/ in the https://github.com/rgoulter/keyboard-labs repository.
