 ### Bosch BMP390 Pressure Sensor
 Industrial grade accuracy and stability in pressure measurements are provided by the BMP390 (U3) designed for prolonged use, with a relative accuracy of ±0.03 hPa and an RMS of 0.02 Pa in high-resolution mode. The Bosch BMP390 is suitable for rapid measurements with a sampling rate of 200 Hz, or for low-power use with a sampling rate of 1 Hz, consuming less than 3.2 µA. U3 is controlled via an SPI interface to the BHI260 (U2), on the same bus as the BME688 (U6).
 ### Bosch BMM150 3-Axis Magnetometer
-The Bosch BMM150 (U4) provides accurate 3-axis measurements of the magnetic field with compass-level accuracy. Combined with the BHI260 IMU (U2), Bosch sensor fusion can be used to obtain high-accuracy spatial orientation and motion vectors for detection of heading in autonomous robots as well as predictive maintenance. There is a dedicated I2C connection to the BHI260 (U2), acting as the host.

 ### RGB LED
 An I2C LED driver (U8) drives the RGB LED (DL1) and is capable of a maximum output of 40 mA. It is driven by the ANN-B112 (U5) microcontroller. 
 
 ### USB Bridge
-The SAMD11 microcontroller (U1) is dedicated to act as both the USB bridge as well as the JTAG controller for the ANNA-B112. A logic level translator (U13) acts as an in-between to translate 3.3V logic to 1.8V for the ANNA-B112. The 3.3V voltage is generated from the USB voltage by an LDO (U14).

-The **Arduino Nicla Sense ME** can be powered via micro USB (J7), ESLOV (J5) or VIN. This is converted into the relevant voltages via the BQ2512BAYFPR IC (U9). A Schottky diode provides reverse polarity protection to the USB and ESLOV voltages. When voltage is supplied via the micro USB, a linear 3.3V regulator also provides power to the SAMD11 microcontroller used for programming the board as well as for JTAG and SWD. The LED driver (U8) and RGB Leds (DL1) are driven by a boost voltage of 5V. All other components operate off the 1.8V rail regulated by a buck converter. PMID acts as an OR switch between VIN and BATT and operates the LED driver. All I/O broken out to the pins are fed through a bi-direction voltage translator running at V<sub>DDIO_EXT</sub>.
