# Description

-
Nano 33 BLE is a miniature sized module containing a NINA B306 module, based on Nordic nRF52480 and containing a Cortex M4F and a 9axis 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.

Arduino® Nano 33 BLE is a miniature sized module containing a NINA B306 module, based on Nordic nRF52480 and containing an Arm® Cortex®-M4F and 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.
As all Nano form factor boards, Nano 33 BLE does not have a battery charger but can be powered through USB or headers.

**NOTE:**Arduino Nano 33 BLE only supports 3.3V I/Os and is **NOT** 5V tolerant so please make sure you are not directly connecting 5V signals to this board or it will be damaged. Also, as opposed to Arduino Nano boards that support 5V operation, the 5V pin does NOT supply voltage but is rather connected, through a jumper, to the USB power input.

The Main Processor is a Cortex M4F running at up to 64MHz. Most of its pins are connected to the external headers, however some are reserved for internal communication with the wireless module and the on-board internal I<sup>2</sup>C peripherals (IMU and Crypto).
