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 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.

While the Arduino Nano 33 BLE Sense offers a small, powerful, BT connected development board with all the sensors you may need to design innovative applications.

For an additional ten bucks, the “BLE Sense” adds a slew of sensors: pressure, humidity, digital proximity, ambient light, gesture sensor, and a microphone.

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.

The new lineup is compatible with the original Nano boards and includes the Nano Every, Nano 33 IOT, Nano 33 BLE, and Nano BLE Sense. While often compared to the Raspberry Pi, the Arduino is built ...

At $19, the BLE flavor gets you a 9-axis accelerometer. For an additional ten bucks, the “BLE Sense” adds a slew of sensors: pressure, humidity, digital proximity, ambient light, gesture ...

The Nano 33 BLE Sense (Rev2 in photo) has the same 9-axis swap for Revision 2, and some changes in its other sensors: The microphone was a MP34DT05 (ST) and is now a MP34DT06JTR (ST) in rev 2. Gesture ...
