About the Glhfkbd PCB

Glhfkbd is an open source STM32 PCB design by redhotvengeance, published on GitHub under the MIT license. It is a 2-layer board measuring 296.5 × 103.6 mm, with 130 components from 21 distinct parts.

Its main chip is the STM32F072CBT6, from the STM32 family. Other key parts include the USBLC6-2SC6, TPS2116DRL and XC6206PXXXMR. By type, the board carries 62 diodes, 24 resistors, 22 capacitors, 10 ICs, 4 connectors and 4 fuses.

It belongs with the keyboards designs in this gallery.

From the project

Features: - Extremely minimalist design -- no bevels, no edges, just keys! - Split body, for da ergonomics - Row-staggered, for da muscle memory - A "Y" and "B" key on both halves, for da bad typists - Supports hotswap MX sockets - Fully embedded electronics -- no dev boards! - U

Glhfkbd: common questions

What microcontroller does the Glhfkbd use?

The Glhfkbd is built around the STM32F072CBT6, from the STM32 family.

How big is the Glhfkbd PCB?

The Glhfkbd measures 296.5 × 103.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Glhfkbd?

130 components, from 21 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 Glhfkbd design files?

From the redhotvengeance/glhfkbd 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 Glhfkbd design in my own project?

Yes, under the terms of its MIT license, which redhotvengeance chose for the repository.

Can I test firmware for the Glhfkbd 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.
