IMU Ethernet: common questions

What microcontroller does the IMU Ethernet use?

The IMU Ethernet is built around the STM32F407VETx, from the STM32 family.

How big is the IMU Ethernet PCB?

The IMU Ethernet measures 100 × 40 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the IMU Ethernet?

62 components, from 32 distinct parts. The full bill of materials is listed on this page.

Where can I download the IMU Ethernet design files?

From the embeddedalpha/IMU_Ethernet repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the IMU Ethernet design in my own project?

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

Can I test firmware for the IMU Ethernet 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.
