Primary design files

The KiCad project lives in the ut-ras/Region-5-2017-2018 repository on GitHub; these links point at the commit this page was built from.

Primary: common questions

What microcontroller does the Primary use?

The Primary is built around the Arduino_1pin, from the AVR/Arduino family.

How big is the Primary PCB?

The Primary measures 104.1 × 53.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Primary?

30 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the Primary design files?

From the ut-ras/Region-5-2017-2018 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Primary design in my own project?

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

Can I test firmware for the Primary 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.
