Dtu unicycle: common questions
What microcontroller does the Dtu unicycle use?
The Dtu unicycle is built around the Teensy 4.0, from the NXP family.
How big is the Dtu unicycle PCB?
The Dtu unicycle measures 124.3 × 84 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Dtu unicycle?
36 components, from 22 distinct parts. The full bill of materials is listed on this page.
Where can I download the Dtu unicycle design files?
From the he1k/dtu_unicycle repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Dtu unicycle design in my own project?
The repository has no license, so all rights stay with he1k. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Dtu unicycle 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.
