Ppse hardware: common questions

What microcontroller does the Ppse hardware use?

The Ppse hardware is built around the RP2040, from the RP2040/RP2350 family.

How big is the Ppse hardware PCB?

The Ppse hardware measures 102.2 × 77.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Ppse hardware?

134 components, from 69 distinct parts. The full bill of materials is listed on this page.

Where can I download the Ppse hardware design files?

From the 4137314/ppse-hardware repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Ppse hardware design in my own project?

Yes, under the terms of its GPL-3.0 license, which 4137314 chose for the repository.

Can I test firmware for the Ppse hardware 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.
