Stenokey: common questions

What microcontroller does the Stenokey use?

The Stenokey is built around the Teensy2.0, from the NXP family.

How big is the Stenokey PCB?

The Stenokey measures 219 × 139.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Stenokey?

101 components, from 41 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 Stenokey design files?

From the mike-ady/Stenokey repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Stenokey design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Stenokey 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.
