Other key parts include the TL431DBZ. By type, the board carries 7 resistors, 4 connectors, 1 IC, 1 transistor, 1 diode and 1 capacitor.

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

From the project

Second version of Hacklab's custom built CNC machine

Sergei 2 CNC machine project ============================

This repository contains design files for Hacklab Jyväskylä's CNC machine project. The machine is built out of existing linear assemblies that have been donated to us, and as such it is not readily reproducible. But some of the modules may be useful and in any case this repository contains information for future maintenance of the machine.

Braking shunt: common questions

How big is the Braking shunt PCB?

The Braking shunt measures 80 × 55 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Braking shunt?

15 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the Braking shunt design files?

From the HacklabJKL/sergei_cnc2 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Braking shunt design in my own project?

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