Firmware
Prototype firmware
For now written in Python with QMK for basic HID functionality. It does not include any screen functionality.
Final firmware
The firmware is going to be written in rust (to maximise resource control allowing for more complexity) and will run on a p2p infrastructure with a daemon on the target pc allowing for more advanced macros. The complexity is too big to write without the microcontroller available

Questions
How big is the Hackpad Comms PCB?
It measures 86 × 85 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackpad Comms use?
27 parts. 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 Hackpad Comms KiCad files?
From the Tomko145/comms-pad repository on GitHub, at the commit this page was made from: the board is kicad/Hackpad_Comms.kicad_pcb and its schematic kicad/Hackpad_Comms.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hackpad Comms design in my own project?
Its repository publishes it under the Unlicense licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
