Pdms: common questions
What microcontroller does the Pdms use?
The Pdms is built around the STM32L496ZGT6, from the STM32 family.
How big is the Pdms PCB?
The Pdms measures 102.5 × 113.8 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Pdms?
473 components, from 114 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 Pdms design files?
From the PGRacing/PDM 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 Pdms design in my own project?
The repository has no license, so all rights stay with PGRacing. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Pdms 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.
