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

Power: common questions

What microcontroller does the Power use?

The Power is built around the ATMEGA16M1, from the AVR/Arduino family.

How big is the Power PCB?

The Power measures 66.1 × 84.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Power?

64 components, from 28 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 Power design files?

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

Can I use the Power 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 Power 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.
