Bosch® Bmm150 3-Axis Magnetometer; Rgb Led; Usb Bridge - Arduino Nicla Sense ME Product Reference Manual

Arduino® Nicla Sense ME
4.7 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 the 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.

4.8 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.

4.9 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).
