Teensy: common questions

What microcontroller does the Teensy use?

The Teensy is built around the MAX7313, from the NXP family.

How big is the Teensy PCB?

The Teensy measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Teensy?

58 components, from 31 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 Teensy design files?

From the adeboni/math-camp-synth repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Teensy design in my own project?

Yes, under the terms of its GPL-3.0 license, which adeboni chose for the repository.

Can I test firmware for the Teensy 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.
