Odrive 3.6 Schematic «Exclusive»
The ODrive v3.6 schematic is more than a set of wiring diagrams; it is a comprehensive document that captures the essence of a high-performance, open-source motor controller. By studying the schematic, you gain the ability to repair a damaged USB port, design custom modifications, or even build a motor controller that rivals commercial offerings. The v3.6's open-source heritage ensures that its design principles will continue to educate and inspire the engineering community for years to come, even as newer models emerge.
The board accepts a wide input voltage range (typically 12V to 24V for the 24V version, and 12V to 56V for the 56V version).
Ultra-low resistance (typically 0.5 milliohms), high-precision surface-mount resistors sit between the low-side MOSFET source terminals and the system ground plane.
) and voltage reference are utilized to ensure the ADCs sample current and voltage feedback with minimal thermal or electromagnetic drift. 3. Power Gate Drivers: TI DRV8301
pin on the MCU to suppress high-frequency ripple generated by the power stage. odrive 3.6 schematic
Used for generating Pulse Width Modulation (PWM) signals to the gate drivers.
The schematic begins with the DC input terminal (J1). Key components include:
Given the board's open-source heritage, the most authoritative place to find its design files is the official ODrive Hardware repository on GitHub, hosted at github.com/madcowswe/ODriveHardware . This repository contains the schematic, PCB layout, and mechanical dimensions for the v3.6 board. Although the official hardware documentation page is no longer actively updated, the repository remains the definitive source.
The Odrive 3.6 schematic diagram is available for download in a range of formats, including PDF and Eagle. The board's firmware is also open-source and available for download on the Odrive website. The ODrive v3
The is a high-performance, dual-axis brushless DC (BLDC) motor controller designed for precision motion control in robotics and industrial automation. While it has been succeeded by newer models like the ODrive S1 and Pro, the v3.6 remains a popular choice for high-current applications due to its dual-axis capability and open-source heritage. ODrive 3.6 Hardware Specifications
The gate drivers push signals to the onboard (typically TO-220 packages mounted with heatsinks). These MOSFETs can handle high peak currents, allowing the controller to deliver the massive amounts of torque required in dynamic robotic applications. Power Supply Architecture
Processes telemetry, encoder data, and control algorithms.
Place exposed pad areas on the bottom of the PCB directly under the MOSFETs to allow thermal interface pads to pull heat out into an aluminum heatsink. 7.

The ODrive 3.6 schematic is essentially a refined version of the v3.5 design. It focuses on enabling high-performance for two brushless motors simultaneously. Key Components:
One of the most critical support circuits is the brake resistor network. When a motor is decelerated, it regenerates power, sending current back into the DC bus. The schematic shows the brake resistor circuit: a power MOSFET, controlled by a 20kHz PWM signal from the MCU, switches a large external resistor across the DC bus. By varying the duty cycle of this PWM signal, the effective load on the bus is regulated, allowing the regenerated energy to be safely dissipated as heat. Without this, the voltage on the DC bus could rise to dangerous levels, damaging the power supply.
