Odrive 3.6 Schematic [exclusive]

The schematic reveals a sophisticated multi-rail power system designed to handle high voltages (12V–56V) while generating clean low-voltage supplies for sensitive analog and digital components.

The small voltage drop across these shunts is routed via differential traces directly to the internal programmable-gain operational amplifiers inside the DRV8301.

The ODrive v3.6 schematic can be broken down into several key functional blocks, each critical to the board's performance. odrive 3.6 schematic

An ARM Cortex-M4 microcontroller handles the intense mathematical computations required for FOC, trajectories, and communication protocols simultaneously for two independent motors.

The schematic does not show heatsinks, but it hints at their necessity by specifying copper pour areas under the MOSFETs. Here are the pinouts for the two most

For practical work, having the pinout on-hand is indispensable. Here are the pinouts for the two most important connectors on the ODrive v3.6, derived from official sources.

The traces running from the DRV8301 outputs to the gates of the power MOSFETs carry high-frequency peak currents to charge and discharge the MOSFET gate capacitance.
