The is more than a wiring diagram; it is a textbook on high-performance FOC (Field Oriented Control) design. By understanding the power supply, MCU pinout, gate driver topology, and current sense network, you transform from a user who simply plugs in motors into an engineer who can repair, modify, and optimize the system.
The ODrive 3.6 is widely regarded as a breakthrough open-source motor controller, specifically designed to bring high-performance, low-cost robotics to the masses. Unlike simple hobby ESCs (Electronic Speed Controllers), the ODrive excels at for dual brushless motors, delivering precise torque, velocity, and position control. odrive 3.6 schematic

The ODrive 3.6 schematic incorporates a dedicated brake chopper circuit: By understanding the power supply, MCU pinout, gate
The schematic also shows the three-phase MOSFET bridge for each motor, which works in concert with the DRV8301 to deliver high current to the BLDC motor windings.
The heart of the ODrive v3.6 is the STM32F405RGT6, a powerful ARM Cortex-M4 MCU clocked at 168MHz. The schematic shows it connected to all major peripherals: the three-phase PWM outputs for motor control, ADC channels for current sensing, encoder inputs for position feedback, and communication interfaces like USB, UART, and CAN. For developers, this means custom FOC algorithms can be programmed using ST's ecosystem and the provided schematic. , an ARM Cortex-M4 chip that executes the
The schematic reveals two extremely important circuits for safe operation: the current sensing network and the brake resistor (or power dissipation) circuit.
At the heart of the ODrive 3.6 layout are dual independent motor channels, capable of driving two separate BLDC motors simultaneously. The schematic is primarily split into logic, power regulation, gate driving, and MOSFET switching stages. Gate Drivers and MOSFETs
