README
README.mdFalconia Beacon
Falconia Beacon is an ATTINY816-based, CR2032-powered LED beacon board used to make the Falconia rover visible to the SMCS Pi-in-the-sky satellite.
What It Does
- Blinks onboard LEDs so the satellite can detect the rover location.
- Uses a potentiometer to enable or disable the blinking program.
- Supports I2C control at address
0x42.
Project Layout
-
PCB/
Hardware design and manufacturing assets:- KiCad schematic and PCB files
- 3D models and custom footprints/symbol libraries
- Panelization and production outputs
-
src/
Firmware source flashed to the board by default:- Main beacon firmware and related examples
- Build files (Makefile)
Hardware Summary
- MCU: Microchip ATTINY816
- Power: CR2032 coin cell
- Interface: I2C (address
0x42) - User control: Potentiometer (blink program on/off)
Firmware
The default board firmware lives in src/ and is intended to be the code programmed onto production boards unless otherwise noted.
Typical workflow:
- Build firmware from the
src/directory. - Flash using your ATTINY816 programming setup.
- Validate LED blink behavior and I2C response at address
0x42.
Notes
- Hardware and firmware are versioned together in this repository.
- For board-level updates, start in
PCB/. - For behavior/protocol updates, start in
src/.

Questions
How big is the Panel PCB?
It measures 155 × 71 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Panel use?
395 parts, built around the CH340N, TP4057, YTC1P-6030-01 and BS-02-A1AJ010. 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 Panel KiCad files?
From the PHS-SMCS/Falconia-Beacon repository on GitHub, at the commit this page was made from: the board is PCB/Panel/Panel.kicad_pcb and its schematic PCB/Charger/charger.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Panel design in my own project?
Its repository states no licence, so its author keeps all rights: ask PHS-SMCS before reusing the design.
