Pdmv2: common questions
What microcontroller does the Pdmv2 use?
The Pdmv2 is built around the STM32F042G6U6, from the STM32 family.
How big is the Pdmv2 PCB?
The Pdmv2 measures 94 × 90.2 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Pdmv2?
102 components, from 48 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 Pdmv2 design files?
From the jumper385/pdmv2 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Pdmv2 design in my own project?
The repository has no license, so all rights stay with jumper385. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Pdmv2 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.
