Teensy eurorack: common questions

What microcontroller does the Teensy eurorack use?

The Teensy eurorack is built around the Teensy4.1, from the NXP family.

How big is the Teensy eurorack PCB?

The Teensy eurorack measures 118.1 × 101.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Teensy eurorack?

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

Where can I download the Teensy eurorack design files?

From the newdigate/teensy-eurorack repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Teensy eurorack design in my own project?
