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.
