 ### Processor
-H7's main processor is the dual core STM32H747 (U1) including a Cortex® M7 running at 480 MHz and a Cortex® M4 running at 240 MHz. The two cores communicate via a Remote Procedure Call mechanism that allows calling functions on the other processor seamlessly.

 ### 6-Axis IMU
 It is possible to obtain 3D gyroscope and 3D accelerometer data from the LSM6DSOX 6-axis IMU (U3). In addition to providing such data, it is also possible to do machine learning on the IMU for gesture detection, offloading computation load from the main processor.
