ErgoDoxTW: common questions

What microcontroller does the ErgoDoxTW use?

The ErgoDoxTW is built around the ATmega48A-AU, from the AVR/Arduino family.

How big is the ErgoDoxTW PCB?

The ErgoDoxTW measures 200 × 200 mm and is 1.6002 mm thick.

How many components are on the ErgoDoxTW?

69 components, from 54 distinct parts. The full bill of materials is listed on this page.

Where can I download the ErgoDoxTW design files?

From the semicontinuity/embedded 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?

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

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 AVR/Arduino firmware against it before you order a PCB.
