The KiCad project lives in the MissouriMRR/Race-Timer repository on GitHub; these links point at the commit this page was built from.

Race-Timer: common questions

What microcontroller does the Race-Timer use?

The Race-Timer is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.

How big is the Race-Timer PCB?

The Race-Timer measures 150 × 150 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Race-Timer?

27 components, from 18 distinct parts. The full bill of materials is listed on this page.

Where can I download the Race-Timer design files?

From the MissouriMRR/Race-Timer repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Race-Timer design in my own project?

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

Can I test firmware for the Race-Timer 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.
