EtherCATControllerHP: common questions
What microcontroller does the EtherCATControllerHP use?
The EtherCATControllerHP is built around the STM32F405RGT6, from the STM32 family.
How big is the EtherCATControllerHP PCB?
The EtherCATControllerHP measures 77 × 77 mm, has 6 copper layers and is 1.6 mm thick.
How many components are on the EtherCATControllerHP?
168 components, from 74 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 EtherCATControllerHP 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 EtherCATControllerHP 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 EtherCATControllerHP 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.
