Power Pads

Important

DC+- cannot tolerate reversed polarity, verify all power pad connections before energizing.

Note

The motor phase connections A/B/C can be connected in any order.

Logic Pins

  • Digital mode is a general purpose mode that can be used for these functions: step, dir, enable, encoder index, hall effect encoder, SPI encoder nCS.

  • All GPIO pins are 5V tolerant, except if you power the isolator with 3.3V, then ISOLATED IO inputs are rated to 3.3V nominal.

  • GPIO pins that can be configured by the user are enumerated with Gxx.

Notes

Note

The letter G and the zero padding are not used in odrivetool or the web GUI, i.e. G09 would be represented by only the number 9.

  • 5V outputs: combined draw max 600mA

User Facing Pins (Gxx)

  • Locations for all pins that can be configured using GpioMode.

  • Inputs:

    G0-G02, G04-G09, G11-G12, G14-G16, G18

  • Outputs:

    G0, G03, G10, G13-G17

Note

Inputs and outputs are not mutually exclusive.

CAN IO

  • [1] CAN_GND must be connected to DC- at a single point (system star point) when using the CAN interface. See system grounding scheme for more details.

  • [2] CAN_12V is optional and is used to power the ODrive logic, enabling communication before the main power supply is connected. Allowed voltage range: 10V-14V

FEEDBACK IO

  • [3] GND and 5V+ are filtered (ferrite/capacitor) from DC-.

  • THERMISTOR + has an integrated 1k ohm voltage divider.

  • A/B inputs of ENC0 and ENC1 support a frequency of up to 2.5 MHz (10M counts/s).

Warning

[4] The differential signal pin(s) GO+, G0- are located on J8 AND J14

ISOLATED IO

  • ISO_GND and ISO_VDD must be connected to your other board.

  • ISO_VDD is a power Input to the isolated interface, which you should power with 3.3V or 5V.

  • Input and output levels are 3.3V if you supply 3.3V, and are 5V if you supply 5V. Inputs are not 5V tolerant if you supply 3.3V.

Power Output Instead of Input (requires hardware modification)

You can change the ISO VDD and ISO GND to be power outputs instead, but this will bypass the isolation. This can be useful if you are powering a module that doesn’t have any other connections than to the ODrive, such as an RC receiver. To do this, you can bridge R66 and R64 for 5V output, or R66 and R65 for 3.3V output, on ISO VDD.

MISC IO

  • 3.3V max draw 200mA

  • see Differential Interfaces below.

Warning

[5] Pins G16 and G17 are only rated for 3.3v, they are NOT 5V tolerant.

Differential Interfaces [6]

Pins G0 [clock], G17 [select] and G18 [data] can be used for RS422 differential signals or as single ended connections if only the + side is used. This allows the ODrive Pro to support a wide variety of encoder interfaces, including SSI (RS422 or single ended), BiSS or RS422 SPI (half duplex only). For specific encoder protocols please refer to the Encoders Page.
