RetroPad build123d: common questions

What microcontroller does the RetroPad build123d use?

The RetroPad build123d is built around the ATtiny814-SS, from the AVR/Arduino family.

How many components are on the RetroPad build123d?

27 components, from 11 distinct parts. The full bill of materials is listed on this page.

Where can I download the RetroPad build123d design files?

From the Sanchit0987/RetroPad-build123d repository on GitHub, which has a netlist; the links under Design files point to each one.

Can I use the RetroPad build123d design in my own project?

The repository has no license, so all rights stay with Sanchit0987. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the RetroPad build123d 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.
