About the TMC2660 Driver PCB

TMC2660 Driver is an open source STM32 PCB design by ghent360, published on GitHub under the Custom license license. It is a 4-layer board measuring 36.7 × 39.4 mm, with 23 components from 18 distinct parts.

Its main chip is the STM32F407VET6, from the STM32 family. Other key parts include the 74LVC125 and 24LC64T-I/SN. By type, the board carries 14 capacitors, 4 resistors, 3 ICs and 2 connectors.

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

From the project

32-bit 3D Printer controller board using STM32F407 and replaceable TMC2660/2209 stepper drivers.

PrntrBoard V2 ====================== PrntrBoard V2 is the next iteration of my 3D printer controller design. The V1 was very good, except it had one major drawback - the stepper drivers were soldered on the board which would make the design expensive. This V2 design has 6 replaceable motor drivers. While traditional RAMPS based boards use pin headers to house the driver boards, I'm using PCIe 1x slots. This design has several advantages: + the driver PCB layout can be more flexible as there are fewer constraints on the driver board dimensions + drivers are placed vertically on the board which…

TMC2660 Driver: common questions

What microcontroller does the TMC2660 Driver use?

The TMC2660 Driver is built around the STM32F407VET6, from the STM32 family.

How big is the TMC2660 Driver PCB?

The TMC2660 Driver measures 36.7 × 39.4 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the TMC2660 Driver?

23 components, from 18 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 TMC2660 Driver design files?

From the ghent360/PrntrBoardV2 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 TMC2660 Driver design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the TMC2660 Driver 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.
