INV Boost Controller: common questions

What microcontroller does the INV Boost Controller use?

The INV Boost Controller is built around the STM32G474VETx, from the STM32 family.

How big is the INV Boost Controller PCB?

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

How many components are on the INV Boost Controller?

256 components, from 68 distinct parts. The full bill of materials is listed on this page.

Where can I download the INV Boost 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 Boost 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 Boost 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.
