ODrive Micro is an ultra-compact, high-performance servo motor drive from ODrive Robotics, designed to make precise robot motion easier than ever before. Building on ODrive’s powerful software and mature hardware ecosystem, ODrive Micro enables the next generation of highly integrated robotic applications. Pair it with the brushless motor of your choice, configure it with the plug-and-play web GUI, and build something great!

As a thank you for supporting the campaign, you will be the first to receive your ODrive Micro, and at a discounted price of $79. After the campaign ends, the price will increase to $89.

Any Motor, Any Application

ODrive Micro is engineered for seamless setup and flexible integration. Featuring an onboard magnetic angle sensor, it mounts directly on your motor without requiring a separate encoder. Power it with a 10-30 V source, connect via the convenient daisy-chained CAN connector, and you’re ready to roll!

Got a gearbox with an output encoder? Maybe you can’t use the onboard magnetic angle sensor? No problem! ODrive Micro also supports hall, quadrature, and SPI encoders, allowing both motor commutation and dual-encoder load positioning from external encoders.

Why Micro?

ODrive Robotics was started with one goal in mind – to make precision, affordable, high-power motion control accessible to everyone. We’re thrilled to see ODrive products powering robots in research and industry around the world, enabling the next generation of robotics applications.

Now, we’re condensing ODrive’s decade of motion control expertise into an ultra-miniature form factor, packing up to 180 W of power in just 10 cm². Enjoy the same top-notch reliability and performance as the ODrive Pro and ODrive S1 without the bulk. ODrive’s ecosystem supports CAN communication, boasts robust libraries, and features an intuitive GUI that gets your next project up and running swiftly.

Why Brushless?

Brushless servomotors far outperform the low power density of stepper motors and offer superior longevity and reliability over brushed motors. With closed-loop encoder feedback, ODrive Micros precision surpasses both!

Convert any brushless motor into a high-precision servomotor with the ODrive ecosystem. With ODrive Micro, achieve precision and power in every corner of your robot. From gimbal motors to NEMA BLDCs, gear motors to drone motors, the choice is yours!

Support and Documentation

You can read about ODrive Micro’s specifications on the datasheet. We also provide CAD files. Check out our documentation to learn about our web GUI and python libraries. We offer technical support on our Discord and forum.

Our suite of software tooling is open source, from our Python library to our CAN communication protocols to our Arduino examples. We’ll publish ODrive Micro’s schematics to enable everyone to learn from the Micro and better utilize its capabilities. We will release all related files after campaign orders have been fulfilled.

Manufacturing Plan

Once crowdfunding has completed, we will begin manufacturing, and every ODrive Micro will be put through comprehensive end-of-line factory testing. With 100% test coverage, we’ll ensure high levels of performance right out of the box.

Fulfillment and Logistics

After testing is complete, ODrive Micro will be sent to Crowd Supply’s fulfillment partner, Mouser Electronics, who will distribute orders to backers worldwide. You can learn more about Crowd Supply’s fulfillment service under Ordering, Paying, and Shipping in their guide.

Risks & Challenges

Years of testing and development guarantee ODrive Micro’s reliability. ODrive offers a 1-year manufacturer’s warranty that warrants our products to be free from defects and workmanship for a period of one year from the date of fulfillment.

We designed ODrive Micro from the ground up for maximum reliability and lifespan. It’s been put through thousands of hours of endurance testing, ensuring full performance no matter what task is given. With integrated protection measures ranging from overvoltage and overcurrent protection to encoder calibration validation, ODrive Micro is designed to keep you and your gear safe.
