Arduino Nano 33 Ble Sense with Header-Rev 2 ABX00070

The Arduino Nano 33 BLE Sense is an enhanced version of the original Arduino Nano. It boasts a more powerful processor, the nRF52840 from Nordic Semiconductors, which runs at 64 MHz and features a 32-bit ARM Cortex -M4 CPU. With this upgrade, you can create larger programs compared to the Arduino Uno, as it offers 1MB of program memory, 32 times more than its predecessor. Additionally, the RAM is 128 times larger, allowing for a greater number of variables. Notably, the main processor also includes impressive features such as Bluetooth pairing through NFC and ultra-low power consumption modes.

In terms of size, the Nano 33 BLE Sense holds the title for being Arduino’s smallest AI-enabled board, measuring just 45x18mm. Despite its compact form, it is a completely new board that maintains the familiar form factor. Furthermore, it comes equipped with a variety of built-in sensors.

Note FYI: Arduino officials have replaced LSM9DS1 (9 axis) with a combination of two IMUs (BMI270 – 6 axis IMU and BMM150 – 3 axis IMU).  

Reason for change:

1. The IMU (LSM9DS1), the temperature sensor (HTS221), and the power supply (MPM3610) are replaced due to a shortage of these components.
2. The additional jumper and test points are added to improve the customer experience.
