Donkey racing: common questions

What microcontroller does the Donkey racing use?

The Donkey racing is built around the TEENSY, from the NXP family.

How big is the Donkey racing PCB?

The Donkey racing measures 65 × 59.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Donkey racing?

61 components, from 38 distinct parts. The full bill of materials is listed on this page.

Where can I download the Donkey racing design files?

From the jwatte/donkey_racing repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Donkey racing design in my own project?

Yes, under the terms of its MIT license, which jwatte chose for the repository.

Can I test firmware for the Donkey racing without the hardware?

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