3DotDash: common questions

What microcontroller does the 3DotDash use?

The 3DotDash is built around the ProMicro, from the AVR/Arduino family.

How big is the 3DotDash PCB?

The 3DotDash measures 114.3 × 156 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 3DotDash?

41 components, from 5 distinct parts. The full bill of materials is listed on this page.

Where can I download the 3DotDash design files?

From the aydenvis/Ortho-Minidox-Choch-Switches repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the 3DotDash design in my own project?

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

Can I test firmware for the 3DotDash 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.
