This compact and reliable Nano board is built around the NINA B306 module for BLE and Bluetooth 5 communication; the module is based on the Nordic nRF 52840 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.
This new Rev2 version is improved with the addition of VUSB solder jumper on the top side, as well as with new test point for USB, SWDIO and SWCLK.
Features:
- 9 axis inertial sensor: what makes this board ideal for wearable devices
- humidity, and temperature sensor: to get highly accurate measurements of the environmental conditions
- barometric sensor: you could make a simple weather station
- microphone: to capture and analyse sound in real time
- gesture, proximity, light color and light intensity sensor : estimate the room’s luminosity, but also whether someone is moving close to the board
