Production Progress, Testing, and New Shipping Estimate

by ODrive Team

Hello Crowd Supply Backers!

Production is well underway for the ODrive Micro! We wanted to share an update with you about assembly line testing, as well as share a video from YouTuber Aaed Musa featuring the ODrive Micro!

We also have a new expected fulfillment date. Unfortunately, things have taken a little longer than anticipated, and fulfillment has been delayed by a little over a month. The new expected fulfillment date for Crowd Supply orders is March 10th, 2025. We appreciate your patience and understanding as we work to launch the ODrive Micro. We’re super excited to see what this awesome community is going to build with it!

We worked hard to ensure production-line testing was in place before manufacturing began. To achieve this, we designed and built a custom In-Circuit Testing (ICT) apparatus, which has now been shipped and set up at our contract manufacturer’s facility. This allows us to test every single feature on each unit of the ODrive Micro before they’re shipped, ensuring you have a smooth and seamless setup experience.

As of January 15th, the ICT system is fully operational at the factory, and ODrive Micros are ready to start rolling off the production line!

The first ODrive Micro being programmed at the factory!

We’re using a custom bed-of-nails test jig — this consists of a bunch of precision spring-loaded pins with a fiberglass cradle for the Micro:

Each of the spring-loaded pins, called pogo pins, contact a test pad on the back of the Micro:

All external signals on the Micro are connected to a test pad, as well as a good number of internal signals — this way, we can do everything from testing the voltage regulators, to USB and CAN, to the encoder interfaces, to the motor drive circuitry itself!

All of the test pins get wired to this adapter PCB, which includes circuitry for measuring voltage rails, switching power, and programming the ODrive Micro’s onboard microcontroller. This gets connected to our test PC, which uploads all test results to a database. We even save line-by-line test results, so we can analyze trends and tolerances over time, helping us make more reliable products.

While you wait for your order, check out this video featuring the ODrive Micro by one of our favorite robotics content creators, Aaed Musa. Aaed has used ODrives before in projects like a Capstan Drive actuator, Rubik’s Cube solver, and a robot dog. In his latest video, Aaed built a wheeled bipedal robot using ODrive Micro. We hope it helps get the creative juices flowing!

That’s all for now! Thank you for your support, and we can’t wait for you to experience the ODrive Micro in March.
