Arduino® Nano 33 BLE Rev2
1 / 14 Arduino® Nano 33 BLE Rev2 Modified: 27/02/2024
Product Reference Manual
SKU: ABX00071
Description
The Arduino Nano 33 BLE Rev2* is a miniature-sized module containing a NINA B306 module, based on Nordic
nRF52480 and containing an Arm® Cortex®-M4F. The BMI270 and BMM150 jointly provide a 9-axis IMU. The
module can either be mounted as a DIP component (when mounting pin headers) or as a SMT component, directly
soldering it via the castellated pads.
*Nano 33 BLE Rev2 product has two SKUs:
Without headers (ABX00071)
With headers (ABX00072)
Target Areas
Maker, enhancements, IoT application
