The ODrive 3.6 exists in two voltage variants: the 24V version and the 56V version.
The main connector for these signals is a 20-pin header (J3). Early version confusion between 18-pin and 20-pin connectors has been clarified; the newer v3.6 design uses a 20-pin connector that matches the v3.5 design.
To achieve precise control, the ODrive requires feedback on the rotor's position. The v3.6 is designed to work with various sensors. The primary feedback connectors are J4 (for Encoder) and J5 (for Hall sensors, though many users simply call the main encoder input J4).

The ODrive v3.6's hardware is only half the story; it is defined by its powerful open-source firmware. The board is configured and controlled through a command-line tool called (which requires a Python environment).
: It runs complex math hundreds of times per second to keep the motors smooth and steady.

The ODrive 3.6 schematic separates the high-power traction components from the sensitive 3.3V logic signals. It features a dual-axis design, meaning a single board contains two identical sets of motor driver sub-circuits, all coordinated by a central microcontroller.
