SparkFun 9DoF IMU Breakout - ISM330DHCX, MMC5983MA (Qwiic)

The SparkFun Qwiic 9DoF IMU Breakout combines the high-performance ISM330DHCX 3D digital accelerometer and gyroscope from STMicroelectronics with the highly sensitive MMC5983MA triple-axis magnetometer by MEMSIC to give you an ultra powerful and easy to use Qwiic enabled breakout board. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.

With a full scale acceleration range of ±2/±4/±8/±16g and a wide angular rate range of ±125/±250/±500/±1000/±2000/±4000dps, as well as an unmatched set of embedded features (Machine Learning Core, programmable FSM, FIFO, sensor hub, event decoding and interrupts), the ISM330DHCX delivers high performance at very low power. Add the MMC5983MA, which can measure magnetic fields within the full scale range of ±8 Gauss (G), with 0.25mG/0.0625mG per LSB resolution at 16bits/18bits operation mode and 0.4 mG total RMS noise level and you have Nine Degrees of Freedom on one little board.

The SparkFun Qwiic Connect System is an ecosystem of I²C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
