IMUModule STM32: common questions

What microcontroller does the IMUModule STM32 use?

The IMUModule STM32 is built around the STM32G473RCTX, from the STM32 family.

How big is the IMUModule STM32 PCB?

The IMUModule STM32 measures 25.4 × 53.3 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the IMUModule STM32?

84 components, from 12 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 IMUModule STM32 design files?

From the Kotakku/IMUModule_STM32_PCB 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 IMUModule STM32 design in my own project?

The repository has no license, so all rights stay with Kotakku. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the IMUModule STM32 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.
