Numpad: common questions

What microcontroller does the Numpad use?

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

How big is the Numpad PCB?

The Numpad measures 86.3 × 123.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Numpad?

36 components, from 5 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 Numpad design files?

From the Anayjain1129/PCB-Files repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Numpad design in my own project?

The repository has no license, so all rights stay with Anayjain1129. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Numpad 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.
