- 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|

CAN IMU Firmware v.1.1 (21Kb 26.11.2016)
/!\ We strictly advise to upgrade firmware to all owners of CAN IMU sensor loaded with the 1.0 version of firmware (all items ordered prior to 22.11.2016)!
- Fixed the critical issue with the accidental spin of all motors at startup 1
How to upgrade firmware
To upgrade a firmware in the CAN module, connect module by CAN interface to the board, connect the board to a PC and run SimpleBGC32 GUI. It's better to not connect a battery.
- Go to "Upgrade" tab, open "Connected modules" tab. Press the "Refresh" button to load information about modules.
- Select a required module from the list. GUI will show current hardware, firmware and bootloader versions for each module (excepting GUI prior to 2.62: it shows hardware and bootloader version only).
- Browse for the file containing new firmware. Be careful, flashing improper file will make the device "bricked" and it will be hard to make it alive.
- Press "Flash" button to write firmware.
- Reconnect USB to restart gimbal controller and let him see changes.
- Connect GUI and repeat steps 2, 3 to check that new firmware is working and whole system operates normally.
Information regarding upgrading firmware over I2C interface will be available later.
1 If sensor is connected by the I2C interface, for 100% compatibility it is required to upgrade firmware in the main controller to version 2.61b9 and above.
