This is the Nano 33 BLE (without headers) by Arduino, a 3.3V compatible board that packs an impressive amount of power in the smallest form factor currently on the market, at just 45x18mm. It's an entirely new board that fits comfortably into the familiar Nano form factor, perfect for wearable devices or scientific experiments requiring short-distance wireless communication.
Featuring the nRF52840 from Nordic Semiconductors, a powerful 32-bit ARM® Cortex®-M4 CPU that runs at 64 MHz, the Arduino Nano 33 BLE is a major evolution from the traditional Arduino Nano. This boosted processing power allows you to run larger programs and manage more variables, as it offers 1MB of program memory and 128 times the RAM of its predecessor. Additional features like Bluetooth® pairing via NFC and ultra-low power consumption modes make it even more versatile.
The Nano 33 BLE also integrates a 9-axis inertial measurement unit (IMU), including an accelerometer, a gyroscope, and a magnetometer, each with 3-axis resolution. This makes it an ideal choice for advanced robotics experiments, exercise trackers, digital compasses, and more.
While the Nano 33 BLE functions at 3.3V, it remains a pin-equivalent substitute for your past Arduino Nano projects. However, please ensure your design is 3.3V compatible. Besides voltage, the key differences are a superior processor, a micro-USB connector, and a 9-axis IMU. You can get this board with or without headers for flexible implementation in any design, and with a competitive price due to a revised manufacturing process, it's a perfect time to upgrade.
