INV Discrete Controller: common questions

What microcontroller does the INV Discrete Controller use?

The INV Discrete Controller is built around the STM32H743ZITx, from the STM32 family.

How big is the INV Discrete Controller PCB?

The INV Discrete Controller measures 100 × 100 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the INV Discrete Controller?

351 components, from 107 distinct parts. The full bill of materials is listed on this page.

Where can I download the INV Discrete Controller design files?

From the NTURacingTeam/nturt_kicad_EP7 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 Discrete Controller 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 Discrete Controller 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.
