PDM v3.0 - Top MCU: common questions
What microcontroller does the PDM v3.0 - Top MCU use?
The PDM v3.0 - Top MCU is built around the C131990, from the STM32 family.
How big is the PDM v3.0 - Top MCU PCB?
The PDM v3.0 - Top MCU measures 133.2 × 90.6 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the PDM v3.0 - Top MCU?
193 components, from 79 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 PDM v3.0 - Top MCU design files?
From the LHRIC/Monorepo-26-27 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the PDM v3.0 - Top MCU design in my own project?
The repository has no license, so all rights stay with LHRIC. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the PDM v3.0 - Top MCU 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.
