Digimuser Board: common questions
What microcontroller does the Digimuser Board use?
The Digimuser Board is built around the Teensy4.0, from the NXP family.
How big is the Digimuser Board?
The Digimuser Board measures 60.2 × 38.7 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Digimuser Board?
71 components, from 35 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 Digimuser Board design files?
From the piercehowell/DIGIMUSER repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Digimuser Board design in my own project?
Yes, under the terms of its MIT license, which piercehowell chose for the repository.
Can I test firmware for the Digimuser Board 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.
