PunctualPad: common questions

What microcontroller does the PunctualPad use?

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

How big is the PunctualPad PCB?

The PunctualPad measures 61.9 × 64.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PunctualPad?

9 components, from 3 distinct parts. The full bill of materials is listed on this page.

Where can I download the PunctualPad design files?

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

Can I use the PunctualPad design in my own project?

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

Can I test firmware for the PunctualPad 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.
