Questions
How big is the Communicator pcb PCB?
It measures 148 × 81 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Communicator pcb use?
58 parts, built around the ESP32-S3-WROOM-1-N8, AP2112K-3.3, 1N5819WS and DMG2305UX. 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 Communicator pcb KiCad files?
From the Hack-a-Day/2025-Communicator_Badge repository on GitHub, at the commit this page was made from: the board is hardware/communicator_pcb/communicator_pcb.kicad_pcb and its schematic hardware/communicator_front/front_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Communicator pcb design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
