HACKPAD: common questions

What microcontroller does the HACKPAD use?

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

How big is the HACKPAD PCB?

The HACKPAD measures 43.3 × 35.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the HACKPAD?

7 components, from 3 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the HACKPAD design files?

From the Kareem993-cmd/KemoPad repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the HACKPAD design in my own project?

The repository has no license, so all rights stay with Kareem993-cmd. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the HACKPAD 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.
