About the EaserCAT-7000 PCB

EaserCAT-7000 is an open source STM32 PCB design by MetalMusings, published on GitHub. It is a 2-layer board measuring 112.5 × 65.6 mm, with 134 components from 50 distinct parts.

Its main chip is the STM32F407VGT6, from the STM32 family. Other key parts include the TLP292-4, AT24CS32-SSHM, LAN9252_PT and AMS1117-3.3. By type, the board carries 35 resistors, 34 diodes, 31 capacitors, 14 connectors, 8 ICs and 2 crystals.

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

From the project

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

EaserCAT-7000: common questions

What microcontroller does the EaserCAT-7000 use?

The EaserCAT-7000 is built around the STM32F407VGT6, from the STM32 family.

How big is the EaserCAT-7000 PCB?

The EaserCAT-7000 measures 112.5 × 65.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the EaserCAT-7000?

134 components, from 50 distinct parts. The full bill of materials is listed on this page.

Where can I download the EaserCAT-7000 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 EaserCAT-7000 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 EaserCAT-7000 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.
