INV MainBoard STM: common questions
What microcontroller does the INV MainBoard STM use?
The INV MainBoard STM is built around the STM32H743ZITx, from the STM32 family.
How big is the INV MainBoard STM PCB?
The INV MainBoard STM measures 100 × 92 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the INV MainBoard STM?
287 components, from 95 distinct parts. The full bill of materials is listed on this page.
Where can I download the INV MainBoard STM design files?
From the NTURacingTeam/nturt_kicad repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the INV MainBoard STM design in my own project?
The repository has no license, so all rights stay with NTURacingTeam. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the INV MainBoard STM 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.
