EtherCATSTM32: common questions
What microcontroller does the EtherCATSTM32 use?
The EtherCATSTM32 is built around the STM32F405RGT6, from the STM32 family.
How big is the EtherCATSTM32 PCB?
The EtherCATSTM32 measures 50 × 50 mm, has 6 copper layers and is 1.6 mm thick.
How many components are on the EtherCATSTM32?
157 components, from 75 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 EtherCATSTM32 design files?
From the kscalelabs/motor-controller 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 EtherCATSTM32 design in my own project?
The repository has no license, so all rights stay with kscalelabs. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the EtherCATSTM32 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.
