About the Ethercat stm32 PCB

Ethercat stm32 is an open source STM32 PCB design by MetalMusings, published on GitHub. It is a 4-layer board measuring 89.9 × 59.2 mm, with 134 components from 38 distinct parts.

Its main chip is the STM32F407VGT6, from the STM32 family. Other key parts include the LAN9252_PT, AT24CS32-SSHM and AMS1117-3.3. By type, the board carries 55 capacitors, 46 resistors, 14 connectors, 4 ICs, 3 diodes and 2 crystals.

It belongs with the robotics & motion designs in this gallery.

Documentation accompanying the "Make My Own EtherCAT device" video serie on Youtube.

This repository contains the EtherCAT devices I have designed, built and put in use in linuxcnc.

Everything should be here: - Schematics, PCB layouts, and what is needed to build the boards. - Software tools to create an ESI-file and program the ESC eeprom. - Software tools to create the application running on a STM32F407VG. - A big learning curve is hidden in here as well

Ethercat stm32: common questions

What microcontroller does the Ethercat stm32 use?

The Ethercat stm32 is built around the STM32F407VGT6, from the STM32 family.

How big is the Ethercat stm32 PCB?

The Ethercat stm32 measures 89.9 × 59.2 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Ethercat stm32?

134 components, from 38 distinct parts. The full bill of materials is listed on this page.

Where can I download the Ethercat stm32 design files?

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

Can I use the Ethercat stm32 design in my own project?

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

Can I test firmware for the Ethercat 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.
