Flashing Firmware
-
Install and launch QMK Toolbox
-
Connect PCB via USB. Hold down reset button to enter bootloader
-
Under 'Local file' open firmware/void_voidhhkb_via.bin. Everything else can be left as default (MCU is STM32F072 / STM32 DFU — QMK Toolbox auto-detects it in bootloader mode)
-
Click Flash!
-
Unplug and plug in again to complete set up
Using VIA
Temp instructions until I get around to merging files into QMK repo...
-
To edit keymap in via open web page and select 'Design' on the top ribbon
-
Click 'Load Draft Definition' and load '/firmware/voidhhkb/via.json'
Build your own firmware
- Files have been included under 'firmware' if you want to build the bin files yourself.
- This is fairly trivial to do by following the QMK Tutorial

Questions
How big is the VoidHHKB Solder PCB?
It measures 286.4 × 96.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the VoidHHKB Solder use?
163 parts, built around the STM32F072CBT6, 1N4148W, NSMD050 and PRTR5V0U2X. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the VoidHHKB Solder KiCad files?
From the hungrygeek/HSKB repository on GitHub, at the commit this page was made from: the board is PCB Files/VoidHHKB-Solder/VoidHHKB-Solder.kicad_pcb and its schematic PCB Files/VoidHHKB-Hotswap/Matrix.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the VoidHHKB Solder design in my own project?
Its repository states no licence, so its author keeps all rights: ask hungrygeek before reusing the design.
