 ### Neural Decision Processor
 The Arduino® Nicla Voice integrates a Neural Decision Processor™ NDP120 from Syntiant® (U3).The NDP120 leverages Syntiant Core 2™ ultra-low-power deep neural network inference engine to move larger neural networks into always-on domains with capacity to run multiple application simultaneously with minial power consumption, including beamforming, echo-cancellation and noise suppression, keyword spotting and event detection.
+
 ### Microcontroller
 The Arduino® Nicla Voice is powered by a nRF52832 SoC within the ANNA-B112 module (MD1). The nRF52832 SoC is built around an ARM® Cortex-M4 microcontroller with floating point unit running at 64 MHz. Sketches are stored inside the nRF52832 internal 512 KB FLASH which is shared with the bootloader. 64 KB SRAM is available to the user. The ANNA-B112 acts as the SPI host for the data logging 16MB flash (U7) and the BHI260 6-axis IMU (U5). It is also the secondary for the BHI260 (U5) I2C and SPI connection. While the module itself runs at 1.8V, a level shifter can adjust the logic level between 1.8V and 3.3V depending on the LDO set in BQ25120 (U9). An external oscillator (Y1) provides a 32 KHz signal.

 ### Bosch BMM150 3-Axis Magnetometer
 The Bosch BMM150 (U4) provides accurate 3-axis measurements of 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 a LDO (U14).
