ErgoDoxTW: common questions
What microcontroller does the ErgoDoxTW use?
The ErgoDoxTW is built around the TEENSY2.0, from the NXP family.
How big is the ErgoDoxTW PCB?
The ErgoDoxTW measures 182.8 × 158.9 mm and is 1.6002 mm thick.
How many components are on the ErgoDoxTW?
73 components, from 58 distinct parts. The full bill of materials is listed on this page.
Where can I download the ErgoDoxTW design files?
From the haway/ErgoDoxTW repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the ErgoDoxTW design in my own project?
Yes, under the terms of its LGPL-3.0 license, which haway chose for the repository.
Can I test firmware for the ErgoDoxTW 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.
