OpenPNP mobo: common questions
What microcontroller does the OpenPNP mobo use?
The OpenPNP mobo is built around the STM32F407VET6, from the STM32 family.
How big is the OpenPNP mobo PCB?
The OpenPNP mobo measures 180 × 140 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the OpenPNP mobo?
382 components, from 53 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 OpenPNP mobo design files?
From the jaytektas/openPNP_mobo 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 OpenPNP mobo design in my own project?
The repository has no license, so all rights stay with jaytektas. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the OpenPNP mobo 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.
