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 Bluetooth is managed by a NINA B306 module.
The IMU is a LSM9DS1 and it is managed through I2C.
The LPS22HB reads barometric pressure and environmental temperature.
The HTS221 senses relative humidity.
The ADPS-9960 is a digital proximity, ambient light, RGB and gesture sensor.
The MP34DT05 is the digital microphone
Crypto keys are managed by the ATECC608A crypto chip.
The board has a two 15 pins connectors - one on each side -, pin to pin compatible with the original Arduino Nano.
