AmethystHackpad: common questions

What microcontroller does the AmethystHackpad use?

The AmethystHackpad is built around the XIAO-RP2040-DIP, from the RP2040/RP2350 family.

How big is the AmethystHackpad PCB?

The AmethystHackpad measures 80.8 × 99.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the AmethystHackpad?

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

Where can I download the AmethystHackpad design files?

From the amethyst-2/AmethystHackpad repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the AmethystHackpad design in my own project?

The repository has no license, so all rights stay with amethyst-2. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the AmethystHackpad without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
