Wiring Diagrams for VESC Builds

Wiring diagrams are like visual blueprints that show how electrical components are connected within a circuit. They use symbols to represent different components, such as batteries, switches, and controllers, and lines to illustrate the wires that connect them.

:warning: DISCLAIMER: The VESC Bible is currently being republished and rewritten to encompass all necessary beginner guides. All guides with a beta tag are still preliminary and need to be vetted and reviewed by VESC experts.

For beginners embarking on VESC builds, wiring diagrams are absolutely crucial for several reasons:

  • Understanding the Circuit: Wiring diagrams provide a clear and concise way to understand how the different components in a VESC system interact with each other. They show the flow of electricity through the circuit, helping beginners grasp the overall functionality.
  • Safe Assembly: By following a wiring diagram, beginners can ensure that components are connected correctly, minimising the risk of shorts, overloads, or damage to sensitive electronics. This is especially important when working with high-voltage battery packs, where mistakes can lead to dangerous consequences.
  • Troubleshooting: If a problem arises during the build or operation, a wiring diagram can be invaluable for troubleshooting. It helps identify potential problem areas and makes it easier to trace wires and check connections for faults.

Resources for Wiring Diagrams

Finding reliable and accurate wiring diagrams is essential for successful VESC builds. Here are some key resources where beginners can find this information:

  • PEV.dev: Check out the tag wiring and wiring-diagram for all tutorials that include wiring diagrams. Once you open the tag, you can use the search in the top right to include the tag in your query
  • Manufacturer Websites: Many VESC controller and component manufacturers provide detailed wiring diagrams and technical specifications on their websites. Always refer to the official documentation for the specific components you are using.
  • VESCify Discord: This Discord server is a vibrant community of VESC builders and experts. You can wiring diagrams shared there by community members.
  • The Board Garage (YouTube Channel): The Board Garage offers informative videos on various aspects of VESC builds, including BMS setup and configuration. While they may not always provide detailed wiring diagrams, their videos can help visualise the connections and understand the overall wiring process.

When using wiring diagrams, it’s essential to:

  • Match the Diagram to Your Components: Make sure the wiring diagram you are using corresponds exactly to the VESC controller, BMS, motor, and other components in your build. Different components may have different pinouts and connection requirements.
  • Double-Check All Connections: Before powering on your VESC system, carefully double-check all connections against the wiring diagram to ensure accuracy and prevent potential damage.
  • Seek Assistance If Needed: If you encounter difficulties understanding a wiring diagram or have any doubts, don’t hesitate to seek help from experienced VESC builders or consult the resources mentioned above. See Verified Vendors and Builders section to find a builder near you.
