IoT Device Prototyping with STMicroelectronics Nucleo Development Boards – Day 2

Today we will build an Inertial Measurement Unit (IMU) that is based on the NUCLEO-U575ZI-Q. The NUCLEO-U575ZI-Q is a hardware compilation of all of the necessary passive and active components required to support the on-board STM32U575ZI microcontroller. The first order of business within today's lecture involves assembling the IMU sensor hardware. The IMU sensor hardware consists of a 9-Axis absolute orientation sensor module a crystal and various resistors and capacitors. All of the aforementioned components will be placed on a custom printed circuit board. The custom IMU sensor printed circuit board will be designed to meet the MikroElektronika click specifications. The NUCLEO-U575ZI-Q is equipped with a set of female headers that are pinned out to accommodate a standard ARDUINO shield. We won’t be doing anything ARDUINO as far as coding is concerned but we will definitely take advantage of the NUCLEO-U575ZI-Q's ARDUINO pin set. Designing and fabricating a custom ARDUINO shield to support our new IMU sensor click will be our next hardware assembly task. Once the custom IMU hardware has been assembled we will code the IMU click driver. The raw IMU data will need to be moved to an IoT endpoint for processing or display. We will choose a suitable data transfer method and write the necessary C code to display the IMU data.
