PocketPD HW: common questions

What microcontroller does the PocketPD HW use?

The PocketPD HW is built around the RP2040, from the RP2040/RP2350 family.

How big is the PocketPD HW PCB?

The PocketPD HW measures 50 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PocketPD HW?

81 components, from 34 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 PocketPD HW design files?

From the CentyLab/PocketPD_HW 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 PocketPD HW design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which CentyLab chose for the repository.

Can I test firmware for the PocketPD HW 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.
