Falconia 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:

1. Build firmware from the src/ directory.
2. Flash using your ATTINY816 programming setup.
3. Validate LED blink behavior and I2C response at address 0x42.

Notes

• Hardware and firmware are versioned together in this repository.
