The Arduino Nano 33 BLE Rev2 is a significant leap forward in the world of microcontroller boards, designed to empower a diverse array of projects with its advanced capabilities.

Arduino Nano 33 BLE is also ideal for automation projects thanks to the multiprotocol BT 5.0 radio.

The Nano 33 BLE costs $19 and as the name suggests its key feature is Bluetooth support, making it ideal for "short range BT interactions and power-savvy projects".

Ride data from the accelerometer on an Arduino Nano 33 BLE Sense was captured on a smartphone via Arduino Science Journal.

Arduino expands its Nano board offering, with new varieties addressing Bluetooth, sensors, and the IoT. The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328P.

Arduino has bought out second revisions of its Nano 33 BLE and Nano 33 BLE Sense bluetooth-equipped microcontroller boards, keeping the sensor mix, but changing several of the sensor ICs.

Getting started with BLE is easier than ever. T.K. Hareendran uses an inexpensive Texas Instruments CC2541 based module, Arduino, and Android to get connected.

The new Nano design continues the legacy of Arduino boards being prototype friendly, but adds the ability to include the boards in a product design based on surface mount assembly.
