- CAN bus provides more reliable and error free connection compared to the I2C, not limited in length. CAN bus is supported in "Extended" and "Pro" versions of SBGC32 controller.
- I2C port compatible with the regular SBGC32 IMU cable and all SBGC32 controllers.
- EEPROM to store calibration data.
- New 6-axis sensor ICM20608 from InveSense has better performance compared to the old MPU-6050.
- Additional I2C and UART interfaces for the external device connectivity (to be used in future versions of firmware).
- Compact size. Mounting holes are compatible with the old SBGC32 IMU. Optional box.
For proper functionality of CAN IMU, you need the firmware version 2.61b2 or above.
|Size of the board||25×25 mm|
|Distance between the mounting holes||14.2 mm|
|Diameter of the mounting holes||3 mm|

The first revision of this module has a problem: when it is connected by the long cable (about 1m or longer) there is a risk to burn out internal 3.3V voltage regulator when connector is plugged into powered board, or when the main power is turning ON/OFF. The reason is transient voltage on the +5V line. To fix this problem, a Zenner diode BZT52C5V6T should be installed (replacing a capacitor C8 or in parallel to it) as shown on pictures below:
