ESC 3kW control board / initial placement: common questions

What microcontroller does the ESC 3kW control board / initial placement use?

The ESC 3kW control board / initial placement is built around the STM32G474RET3, from the STM32 family.

How big is the ESC 3kW control board / initial placement?

The ESC 3kW control board / initial placement measures 100 × 80 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the ESC 3kW control board / initial placement?

38 components, from 27 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESC 3kW control board / initial placement design files?

From the mekiciepcas/ESC-Ai repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the ESC 3kW control board / initial placement design in my own project?
