Description

Module13.2 ODrive is a high-performance servo motor driver module launched by M5Stack, based on the open-source motion control solution ODrive. It supports control of a single three-phase servo motor, with a peak drive current of up to 5A. While offering high-speed motor control capability, it also provides an encoder signal interface, which enables high-precision motion control and positioning. The module uses a UART communication interface and is compatible with the official ODrive configuration tool and protocol (via the host tool, various motor motion modes can be configured to make motor operation smoother and more stable).

Features

  • Supports single three-phase servo motor drive
  • Peak drive current 5A
  • DC 12 ~ 24V power input interface (requires adapter output current up to 5A)
  • Communication interface: UART
  • Integrated encoder signal interface

Includes

  • 1 x Module13.2 ODrive
  • 1 x 3.96-3P Terminal
  • 1 x 3.96-2P Terminal
  • 1 x 2.54-5P Terminal (with cable)

Applications

  • High-precision motion control
  • Servo motor drive

Example Description
This example uses the ODrive module to control a servo motor for high-speed and precise rotation. Note: Before use, you need to configure relevant parameters using ODriveTool according to the connected motor model.

ODriveTool

odrivetool is the configuration and debugging software paired with ODrive. It can be used to configure motor parameters. This tutorial demonstrates how to install and use odrivetool on the Linux platform.
  • Use the following command to install odrivetool v0.5.1. Environment requirement: python3.
pip3 install odrive==0.5.1.post0
  • Add ~/.local/bin to the system environment variable. Execute the following command, and insert export PATH=$PATH:~/.local/bin to the end of the text.
vim ~/.bashrc
  • Execute odrivetool in the command line to run the tool. Connect the ODrive module to the computer and wait for odrivetool to recognize it. After successful connection, enter odrv0.vbus_voltage to test and get the driver board voltage.
$odrivertool
