AP33772S CircuitPython Library -> Big thanks to @hansendc

Calling usbpd.displayProfiles() without Serial.begin() can soft-brick your PicoPD. Causing the IC to be non-recognizable by your computer. You will have to use PicoProbe to reflash the chip. Check out @Patronics PicoProbePCB if you would like to make a stable fixture for firmware debugging.

If you want to use PicoPD Pro as an AP33772S evalulation board with your own micro-controller, flash the board with AP33772SEval.uf2** using the drag and drop method. This firmware will config GP0 and GP1 as INPUT to prevent I2C interferance with…

PicoPD Pro: common questions

What microcontroller does the PicoPD Pro use?

The PicoPD Pro is built around the RP2040, from the RP2040/RP2350 family.

How big is the PicoPD Pro PCB?

The PicoPD Pro measures 20.5 × 50.8 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the PicoPD Pro?

61 components, from 26 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 PicoPD Pro design files?

From the CentyLab/PicoPD_Pro 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 PicoPD Pro design in my own project?

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

Can I test firmware for the PicoPD Pro 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.
