Getting the code
This repository contains Git submodules that must be cloned to be able to assemble the ORGNET application's code and emulate the Organiser II's firmware. To clone this repository, run:
git clone --recurse-submodules https://github.com/James-Livesey/ORGNETBuilding and running
To build ORGNET's firmware and application, run:
./build.shRunning this script without any arguments will also upload the firmware and application build to the RP2350 over USB.
To test ORGNET's application in an emulator, run:
pushd app; ./build.sh --test; popdParts

Questions
How big is the ORGNET PCB?
It measures 21 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ORGNET use?
43 parts, built around the RP2350A, W25Q128JVPIQ, SN74LVC8T245PW and AP2112K-3.3. 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 ORGNET KiCad files?
From the James-Livesey/ORGNET repository on GitHub, at the commit this page was made from: the board is hardware/ORGNET.kicad_pcb and its schematic hardware/ORGNET.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ORGNET 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).
