ODrive Comparison Table

Below is an comparison of common hardware specifications and features across the products in the ODrive lineup. Please note the ODrive v3.6 is approaching its end of life, and strongly recommended against for new and existing designs. We recommend the ODrive S1 as a single-axis replacement for the ODrive v3.6, providing a near direct superset of features and capabilities.

  • [1] Specified with heatspreader plate and nominal forced air cooling. Over 100A continuous current possible with proper cooling

  • [2] Peak current is limited based on bus voltage. See S1 derating curve for more information.

  • [3] Effective utilizable DC bus voltage percentage. For instance, an ODrive S1 with a 100 RPM/V motor at a 48V bus voltage has a maximum speed of 48*100*0.78 = 3744 RPM.

  • [4] MOSI pin not available, see the Micro datasheet for more information

  • [5] CAN-FD support available in future firmware update

  • [6] CAN powered through DC- by default for “pseudo-isolation”. User modification required for galvanic isolation, units with galvanic isolation by default available upon request.
