HackClubMicropad: common questions

What microcontroller does the HackClubMicropad use?

The HackClubMicropad is built around the 1597-102010550-ND, from the RP2040/RP2350 family.

How big is the HackClubMicropad PCB?

The HackClubMicropad measures 100 × 100 mm, has 2 copper layers and is 1.580794 mm thick.

How many components are on the HackClubMicropad?

30 components, from 10 distinct parts. The full bill of materials is listed on this page.

Where can I download the HackClubMicropad design files?

From the Hamstersarus/HackClubMicropad repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the HackClubMicropad design in my own project?

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

Can I test firmware for the HackClubMicropad 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.
