Wakame keyboard: common questions
What microcontroller does the Wakame keyboard use?
The Wakame keyboard is built around the STM32G431K8Tx, from the STM32 family.
How big is the Wakame keyboard PCB?
The Wakame keyboard measures 293 × 120 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Wakame keyboard?
354 components, from 100 distinct parts. The full bill of materials is listed on this page.
Where can I download the Wakame keyboard design files?
From the Cacaomeme/wakame_keyboard repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Wakame keyboard design in my own project?
The repository has no license, so all rights stay with Cacaomeme. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Wakame keyboard without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
