Stm32 mech keyboard: common questions
What microcontroller does the Stm32 mech keyboard use?
The Stm32 mech keyboard is built around the STM32F042C6Tx, from the STM32 family.
How big is the Stm32 mech keyboard PCB?
The Stm32 mech keyboard measures 285 × 94.6 mm, has 2 copper layers and is 1.6002 mm thick.
How many components are on the Stm32 mech keyboard?
233 components, from 154 distinct parts. The full bill of materials is listed on this page.
Where can I download the Stm32 mech keyboard design files?
From the julbouln/stm32_mech_keyboard repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Stm32 mech keyboard design in my own project?
