Peak Current vs DC voltage

ODrive S1 Peak Current vs DC voltage. The firmware limits motor current according to this curve depending on dc_bus_overvoltage_trip_level.

CAD

The ODrive S1 CAD model is available on the ODrive S1 OnShape page.

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 150mA

  • 3.3V output: max draw 150mA

  • [1] 5V and 3.3V can be switched on and off internally. (feature coming soon!)

  • The RS485 and SPI feedback interfaces are mutually exclusive on S1.

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

  • [2] 12V in is optional and is used to power the ODrive logic, enabling communication before the main power supply is connected. Allowed voltage range: 10V-14V

  • [3] GNC NC offers a common connection for the CAN bus ground, it is not connected internally

  • [4] Differential interface used for RS-485 encoders.

User Facing Pins (Gxx)

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

  • Inputs:

    G0-G03, G06, G09-G12

  • Outputs:

    G0-G03, G05, G07-G11

Note

Inputs and outputs are not mutually exclusive.

ISOLATED IO (G05-G08)

  • GND ISO and V+ ISO must be connected to your other board.

  • V+ ISO 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.

  • UART: (TX)-Transmit data from ODrive, (RX)-Recieve data to ODrive.
