Flight computer: common questions

What microcontroller does the Flight computer use?

The Flight computer is built around the ATMEGA328P-AU, from the AVR/Arduino family.

How big is the Flight computer PCB?

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

How many components are on the Flight computer?

36 components, from 29 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 Flight computer design files?

From the wFairmanOlin/OlinRocketryClub repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Flight computer design in my own project?

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

Can I test firmware for the Flight computer 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.
