Pdk prog: common questions

What microcontroller does the Pdk prog use?

The Pdk prog is built around the C81720, from the STM32 family.

How big is the Pdk prog PCB?

The Pdk prog measures 42 × 37 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pdk prog?

56 components, from 25 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 Pdk prog design files?

From the brainsmoke/pdk_prog 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 Pdk prog design in my own project?

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

Can I test firmware for the Pdk prog 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.
