ODrive Micro Datasheet
The ODrive Micro brings the high-performance motor control of the ODrive lineup to an ultra-miniature form factor, providing up to 100W continuous power in a tiny 32mm x 32mm footprint.
A CAN interface (hardware ready for CAN-FD, firmware planned) and an onboard 12-bit magnetic encoder allows for back-of-motor mounting, creating compact and high-precision actuators.

The ODrive Micro does not have a dedicated SPI MOSI pin. The encoder SPI MOSI pin must be connected to either VCC or GND depending on the model:
AMS, CUI, RLS Orbis encoders: Connect MOSI to VCC.
MA702/MA732 Encoders: Connect MOSI to GND.
CAN Termination and Power
By default, CAN PWR and CAN GND are passthroughs
CAN PWR and CAN GND can be connected to DC+/DC- by bridging the “J2/J3 ALT DC” solder jumpers on the bottom of the board. Note that DC+/DC- should not be connected at the same time as CAN PWR / CAN GND if this configuration is used.
A 120-ohm CAN termination resistor can be enabled by bridging the “CAN 120R” solder jumper on the bottom of the board
This allows for multiple daisy-chained ODrive Micros. Note that the internal CAN PWR / CAN GND passthrough is limited to 1A of current.
