The KiCad project lives in the BehrensG/ETH1CLCR2 repository on GitHub; these links point at the commit this page was built from.

ETH1CLCR2: common questions

What microcontroller does the ETH1CLCR2 use?

The ETH1CLCR2 is built around the STM32H743ZI, from the STM32 family.

How big is the ETH1CLCR2 PCB?

The ETH1CLCR2 measures 160 × 100 mm, has 6 copper layers and is 1.5 mm thick.

How many components are on the ETH1CLCR2?

591 components, from 157 distinct parts. The full bill of materials is listed on this page.

Where can I download the ETH1CLCR2 design files?

From the BehrensG/ETH1CLCR2 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ETH1CLCR2 design in my own project?

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

Can I test firmware for the ETH1CLCR2 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.
