Arduino Nano 33 BLE Sense

This compact and reliable Nano board is built around the NINA B306 module for BLE and Bluetooth 5 communication; the module is based on Nordic nRF52480 processor that contains a powerful Cortex M4F and the board has a rich set of sensors that allow the creation of innovative and highly interactive designs.
Its architecture, fully compatible with Arduino IDE Online and Offline, has a 9 axis Inertial Measurement Unit (IMU), temperature, pressure, humidity, light, color and even gestures sensors that are managed through our specialized libraries. Its reduced power consumption, compared to other same size boards, together with the NANO form factor opens up a wide range of applications.
This allows the design of wearable devices and gesture based projects that need to communicate to other devices at a close range. Arduino Nano 33 BLE Sense is ideal for interactive automation projects thanks to the multiprotocol BT 5.0 radio.

Dimensions: 45x18mm

Specifications:

• This board is based on the nRF52480 microcontroller.

  Clock	64MHz

  Please note: Arduino Nano 33 BLE only supports 3.3V I/Os and is NOT 5V tolerant so please make sure you are not directly connecting 5V signals to this board or it will be damaged. Also, as opposed to Arduino Nano boards that support 5V operation, the 5V pin does NOT supply voltage but is rather connected, through a jumper, to the USB power input.The IMU is a LSM9DS1 and it is managed through I2C.The HTS221 senses relative humidity.The MP34DT05 is the digital microphoneThe board has a two 15 pins connectors – one on each side -,  pin to pin compatible with the original Arduino Nano.

• On the bottom side of the board, under the communication module, debug signals are arranged as 3×2 test pads with 100 mil pitch. Pin 1 is the bottom left one with the USB connector on the left and the test pads on the right.
• Crypto keys are managed by the ATECC608A crypto chip.
• The ADPS-9960 is a digital proximity, ambient light, RGB and gesture sensor.
• The LPS22HB reads barometric pressure and environmental temperature.
• The Bluetooth is managed by a NINA B306 module.
