From the project

This is my custom made 75% rgb mechanical keyboard

This is my custom made 75% rgb mechanical keyboard, it has per-key lights and hot swapable key switches.

Because i have a laptop and i haven't had any actual separate keyboard experience, so i wanted to have one, and thought it would be nice for me to make my own for flexing on my fellows and solidify my PCB desiging knowledge.

The KiCad project lives in the MohamedAlDeep/RGB-Mechanical-KEEB- repository on GitHub; these links point at the commit this page was built from.

RGB-Mechanical-KEEB-: common questions

What microcontroller does the RGB-Mechanical-KEEB- use?

The RGB-Mechanical-KEEB- is built around the STM32F072CBT6, from the STM32 family.

How big is the RGB-Mechanical-KEEB- PCB?

The RGB-Mechanical-KEEB- measures 315.6 × 164.9 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the RGB-Mechanical-KEEB-?

278 components, from 23 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 RGB-Mechanical-KEEB- design files?

From the MohamedAlDeep/RGB-Mechanical-KEEB- 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 RGB-Mechanical-KEEB- design in my own project?

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

Can I test firmware for the RGB-Mechanical-KEEB- 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.
