Odrive 3.6 Schematic -

Understanding the ODrive 3.6 Schematic The is a high-performance open-source dual-motor controller designed for high-power, high-precision motion control applications. Understanding its schematic is essential for integration, troubleshooting, and custom hardware modifications. The ODrive v3.6 is based on the STMicro STM32F405RG Go to product viewer dialog for this item. microcontroller and TI DRV8301 Go to product viewer dialog for this item. gate drivers. Core Hardware Components

Let’s analyze each block as presented in the (Rev 3.6).

: You can find the base circuit design in the v3.5 schematic PDF hosted on the ODrive Hardware GitHub . odrive 3.6 schematic

The ODrive 3.6 drives two independent brushless motors (Axis 0 and Axis 1). Each axis mirrors the exact same schematic layout, comprised of a dedicated gate driver and a three-phase MOSFET bridge inverter. Gate Driver IC: DRV8301

The ODrive v3.6 remains a landmark achievement in open-source hardware. Its detailed schematic is not just a piece of technical documentation; it is a masterclass in high-performance motor control design. Understanding its core circuits—the STM32F405 brain, the DRV8301 power stage, the current sensing network, and the critical brake resistor—is an education in itself. Understanding the ODrive 3

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.

The board accepts a wide input voltage range (typically 12V to 24V for the 24V version, and 12V to 56V for the 56V version). microcontroller and TI DRV8301 Go to product viewer

The ODrive utilizes this 32-bit ARM Cortex-M4 microchip running at 168 MHz. It features a Floating Point Unit (FPU), which is critical for calculating trigonometric functions required by FOC in real time.
