About the CLN-ClosedLoopNemaDriver PCB

CLN-ClosedLoopNemaDriver is an open source STM32 PCB design by creapunk, published on GitHub under the CC-BY-NC-4.0 license. It is a 4-layer board measuring 38 × 39 mm, with 89 components from 39 distinct parts.

Its main chip is the STM32G431CB, from the STM32 family. Other key parts include the TLE5012B, AT24CS01-XHM, ME6211, H5VU25U and TJA1042. By type, the board carries 33 resistors, 28 capacitors, 9 ICs, 8 connectors, 5 diodes and 2 switches.

It belongs with the robotics & motion designs in this gallery, and the repository also holds 4 earlier revisions of it.

From the project

Compact closed-loop stepper motor driver designed for NEMA motors

- Shorting VMOT when USB is plugged may cause unreversible damage of DCDC - Motor freewheeling when unpowered feature not work because of driver chip architecture - Current sensing may not work pr

The KiCad project lives in the creapunk/CLN-ClosedLoopNemaDriver repository on GitHub; these links point at the commit this page was built from.

CLN-ClosedLoopNemaDriver: common questions

What microcontroller does the CLN-ClosedLoopNemaDriver use?

The CLN-ClosedLoopNemaDriver is built around the STM32G431CB, from the STM32 family.

How big is the CLN-ClosedLoopNemaDriver PCB?

The CLN-ClosedLoopNemaDriver measures 38 × 39 mm, has 4 copper layers and is 1 mm thick.

How many components are on the CLN-ClosedLoopNemaDriver?

89 components, from 39 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 CLN-ClosedLoopNemaDriver design files?

From the creapunk/CLN-ClosedLoopNemaDriver 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 CLN-ClosedLoopNemaDriver design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the CLN-ClosedLoopNemaDriver 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.

Earlier revisions in the repo: CLN17-V2.1, CLN17-V2.0, CLN17-V1.5, CLN17-V1.0
