==Description==

: The [https://docs.arduino.cc/resources/datasheets/ABX00031-datasheet.pdf Arduino Nano 33 BLE Sense] is a powerful board equipped with a microcontroller and a wide variety of sensors. The board can sense movement, acceleration, rotation, barometric pressure, sounds, gestures, proximity, color, and light intensity. To be able to have the TinyML Learning Kit back in stock we produced a Nano 33 BLE Sense without the HTS221 sensor (temperature and humidity), so this version is called "Lite". 

: Nano 33 BLE Sense is a miniature sized module containing a NINA B306 module, based on Nordic nRF52480 and containing a Cortex M4F, a crypto chip which can securely store certificates and pre shared keys and a 9 axis IMU. The module can either be mounted as a DIP component (when mounting pin headers), or as a SMT component, directly soldering it via the castellated pads

:** The APDS-9960 device features advanced Gesture detection, Proximity detection, Digital Ambient Light Sense (ALS) and Color Sense (RGBC). The slim modular package, L 3.94 × W 2.36 × H 1.35 mm, incorporates an IR LED and factory calibrated LED driver for drop-in compatibility with existing footprints.
:* [https://content.arduino.cc/assets/Nano_BLE_Sense_mp34dt05-a.pdf MP34DT05-A MEMS audio sensor omnidirectional digital microphone]
:** The MP34DT05-A is an ultra-compact, low-power, omnidirectional, digital MEMS microphone built with a capacitive sensing element and an IC interface. The sensing element, capable of detecting acoustic waves, is manufactured using a specialized silicon micromachining process dedicated to producing audio sensors. The IC interface is manufactured using a CMOS process that allows designing a dedicated circuit able to provide a digital signal externally in PDM format. The MP34DT05-A is a low-distortion digital microphone with a 64 dB signal-to-noise ratio and –26 dBFS ±3 dB sensitivity.
:* [https://content.arduino.cc/assets/Nano_BLE_Sense_lsm9ds1.pdf LSM9DS1 iNEMO inertial module: 3D accelerometer, 3D gyroscope, 3D magnetometer]
:** The LSM9DS1 is a system-in-package featuring a 3D digital linear acceleration sensor, a 3D digital angular rate sensor, and a 3D digital magnetic sensor. The LSM9DS1 has a linear acceleration full scale of ±2g/±4g/±8/±16 g, a magnetic field full scale of ±4/±8/±12/±16 gauss and an angular rate of ±245/±500/±2000 dps. The LSM9DS1 includes an I2C serial bus interface supporting standard and fast mode (100 kHz and 400 kHz) and an SPI serial standard interface. Magnetic, accelerometer and gyroscope sensing can be enabled or set in power-down mode separately for smart power management.

==Links About Arduino Nano 33 BLE Sense==

: This version of the board was produced without the HST221 humidity and temperature sensor because of chip shortages. This is the [https://store-usa.arduino.cc/products/arduino-nano-33-ble-sense?selectedStore=us# product page at Arduino] for the "TinyML Learning Kit" that includes this version of the board. The kit was developed to accompany the [https://www.edx.org/professional-certificate/harvardx-tiny-machine-learning HarvardX-edX series of courses on TinyML], a branch of AI. ''NB: While edX offers the series as a paid professional certification, it is also available to audit for free.''
