00Key: common questions

What microcontroller does the 00Key use?

The 00Key is built around the Teensy4.1, from the NXP family.

How big is the 00Key PCB?

The 00Key measures 304.8 × 170.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 00Key?

256 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the 00Key design files?

From the ZeroZeroOne-dev/00Key repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the 00Key design in my own project?

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

Can I test firmware for the 00Key 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.
