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.

Here's an interesting way to control an Arduino using data-over-sound, demonstrated by Chirp. They show how to use their SDK to send an RGB value to change the colour of a on-board LED.

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

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, ...

Here's an interesting way to control an Arduino using data-over-sound, demonstrated by Chirp. They show how to use their SDK to send an RGB value to change the colour of a on-board LED.

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.
