README
README.mdThis repo contains the Controllers (firmware, pcb design, printables) that make up part of the Makerspace Access Control System.
The basic principles they follow are:
- Use NFC readers (enrol a fob or card of your choice)
- Receive updates over Wifi, but cached on the controller in flash storage.
- Able to work offline and queue events to send to controller when connectivity established
- Provide log updates to the access controller backend to allow device usage to be logged and tracked.
They're an important part of our Health and Safety obligations to our members, ensuring that only authorised users are able to use (potentially) dangerous hardware.
The documentation is on the wiki (in progress...!)

Questions
How big is the Controller PCB?
It measures 60 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Controller use?
38 parts, built around the W25Q32JVSSIQ, MMBT3906 and IRLL014N. 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 Controller KiCad files?
From the MakerSpaceNewcastle/access-control-gen2 repository on GitHub, at the commit this page was made from: the board is pcb/controller/controller.kicad_pcb and its schematic pcb/controller/controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Controller design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
