/** Class AltIMU_10_v5 is intended to represent the MEMS Inertial & Environmental 
 *  Nucleo Expansion Board with the same name.
 *
 *  The expansion board is featuring basically four IPs:\n
 *  -# a HTS221 Relative Humidity and Temperature Sensor\n
 *  -# a LIS3MDL 3-Axis Magnetometer\n
 *  -# a LPS25H MEMS Pressure Sensor (and Temperature Sensor)\n
 *  -# and a LSM6DS33 3D Acceleromenter and 3D Gyroscope\n
 *
 * The expansion board features also a DIL 24-pin socket which makes it possible
 * to add further MEMS adapters and other sensors (e.g. UV index). 
 *
 * It is intentionally implemented as a singleton because only one
 * AltIMU_10_v5 at a time might be deployed in a HW component stack.\n
 * In order to get the singleton instance you have to call class method `Instance()`, 
 * e.g.:
 * @code
 * // Inertial & Environmental expansion board singleton instance
 * static AltIMU_10_v5 *<TODO>_expansion_board = AltIMU_10_v5::Instance();
 * @endcode
