About the Pd adapter PCB

Pd adapter is an open source STM32 PCB design by fullyautomated, published on GitHub. It is a 4-layer board measuring 45 × 38 mm, with 54 components from 34 distinct parts.

Its main chip is the C80488, from the STM32 family. Other key parts include the C132291 and C191884. By type, the board carries 15 capacitors, 15 resistors, 12 diodes, 5 connectors, 3 ICs and 2 switches.

It belongs with the power & battery and iot & wireless designs in this gallery.

From the project

Fully Automated line of USB-C PD PPS boards

USB-C Programmable Power Supply Source and Sink.

Back side optimized for JLCSMT, front for hand placing.

Ecosystem Idea: - Stackable Ferrets; you can have any\* amount of type C ports you can possibly need. Ferrets can have individual legacy electricity I/O, or can be tied to a single common bus. With the - Configuration Board (top position only) you can monitor power flow and change port settings (source/sink, current and voltage) - this has a management interface (USB UART) and maybe Bluetooth/Wifi with an ESP32. Energy is stored in the - Battery Board; 4s BMS which can be attached to the…

Pd adapter: common questions

What microcontroller does the Pd adapter use?

The Pd adapter is built around the C80488, from the STM32 family.

How big is the Pd adapter PCB?

The Pd adapter measures 45 × 38 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Pd adapter?

54 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 Pd adapter design files?

From the fullyautomated/ferret repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Pd adapter design in my own project?

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

Can I test firmware for the Pd adapter without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
