About the TurboCAN PCB

TurboCAN is an open source STM32 PCB design by henrikssn, published on GitHub. It is a 2-layer board measuring 43 × 43 mm, with 84 components from 47 distinct parts.

Its main chip is the STM32F072CBUX, from the STM32 family. Other key parts include the AP2127N-3.3, TMC2209STEPSTICK, SN65HVD230, TPS54331 and AO3400A. By type, the board carries 31 resistors, 23 capacitors, 11 connectors, 9 ICs, 6 diodes and 3 inductors.

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

From the project

This is the official repository for the TurboCAN controller board, designed specifically for the Voron AfterBurner toolhead but can also be used on similar toolheads using NEMA17 steppers.

This is the official repository for the TurboCAN controller board, designed specifically for the [Voron AfterBurner] toolhead but can also be used on similar toolheads using NEMA17 steppers. The main benefit of this board is the capability to run the toolhead over just 4 wires (CAN, +24V, Ground) which greatly simplifies the wiring in the Voron v1 and v2 models.

TurboCAN: common questions

What microcontroller does the TurboCAN use?

The TurboCAN is built around the STM32F072CBUX, from the STM32 family.

How big is the TurboCAN PCB?

The TurboCAN measures 43 × 43 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the TurboCAN?

84 components, from 47 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 TurboCAN design files?

From the henrikssn/TurboCAN repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the TurboCAN design in my own project?

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

Can I test firmware for the TurboCAN 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.
