Teensy test: common questions

What microcontroller does the Teensy test use?

The Teensy test is built around the Teensy_3.2, from the NXP family.

How big is the Teensy test PCB?

The Teensy test measures 254 × 127 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Teensy test?

363 components, from 83 distinct parts. The full bill of materials is listed on this page.

Where can I download the Teensy test design files?

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

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

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

Can I test firmware for the Teensy test 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.
