The ODrive 3.6 provides a versatile array of I/O for various control methods: General I/O Standard digital/analog pins GPIO_3, GPIO_4 USART2 TX/RX Used for serial communication with controllers like Arduino CANH, CANL High-performance industrial communication M0_A, B, C Motor 0 Phases Connection points for the first BLDC motor M1_A, B, C Motor 1 Phases Connection points for the second BLDC motor AUX Brake Resistor Connection for power resistor to dissipate energy Official Schematic Resources
: Driven by two Texas Instruments DRV8301 gate drivers . These chips act as interpreters, converting the 3.3V logic signals from the STM32 into the higher voltages required to switch the power MOSFETs on and off efficiently. 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
Always match your firmware version to the schematic revision. Loading firmware built for Rev 3 onto a Rev 1 board may cause unexpected behavior if GPIO interrupts changed.
The Serial Wire Debug (SWD) pins are broken out to a header, allowing developers to flash custom firmware or debug the code using tools like ST-Link. 3. High-Power Gate Drivers and MOSFETs The schematic is organized around several key sub-circuits,
The v3.6 schematic features a robust power stage designed to handle significant current and voltage levels.
A precise external crystal oscillator provides the clock signal to ensure tight timing synchronization for pulse-width modulation (PWM) generation and communication.
: External diodes and capacitors generate an elevated voltage ( VGScap V sub cap G cap S end-sub ) to fully saturate the high-side N-channel MOSFETs. Power MOSFET H-Bridge & Current Sensing These chips act as interpreters, converting the 3
However, I can give you a of what the ODrive 3.6 schematic contains, based on publicly available information, open-source hardware documents they have released (like the v3.5–3.6 community materials), and reverse-engineering notes from the maker community.
The edge of the schematic lists all the pins you use to plug in external hardware. 3.5 ODrive Schematic Release
