About the Pigeon PCB

Pigeon is an open source AVR/Arduino PCB design by Olin-Rocketry, published on GitHub. It is a 2-layer board measuring 30 × 40 mm, with 30 components from 19 distinct parts.

Its main chip is the ATmega328-AU, from the AVR/Arduino family. Other key parts include the SK812, LM1117MPX-3.3 and ADXL345. By type, the board carries 10 resistors, 9 capacitors, 4 ICs, 3 diodes, 2 connectors and 1 crystal.

The KiCad project lives in the Olin-Rocketry/pigeon repository on GitHub; these links point at the commit this page was built from.

Pigeon: common questions

What microcontroller does the Pigeon use?

The Pigeon is built around the ATmega328-AU, from the AVR/Arduino family.

How big is the Pigeon PCB?

The Pigeon measures 30 × 40 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pigeon?

30 components, from 19 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Pigeon design files?

From the Olin-Rocketry/pigeon repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Pigeon design in my own project?

The repository has no license, so all rights stay with Olin-Rocketry. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Pigeon without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
