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.

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

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

The Arduino Nano and Uno are equipped with very similar processors (the chip that essentially serves as the brain of the board). The Nano features an ATmega328, while the Uno sports an 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.

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".

The Arduino team announced the launch of four new Nano boards: Arduino Nano Every, "perfect for everyday projects"; Arduino Nano 33 IoT, "small, secure, and Internet-connected"; Arduino Nano 33 BLE, ...

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.
