Product Reference Manual
SKU: ABX00027
Description
The Arduino® Nano 33 IoT and Arduino Nano 33 IoT with headers are a miniature sized module containing a Cortex M0+ SAMD21
processor, a Wi-Fi® + Bluetooth® module based on ESP32, a crypto chip which can securely store certificates and pre-shared keys and a 6
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.

USB or headers. NOTE: Nano 33 IoT and Nano 33 IoT with headers 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. - Page 6 Arduino® Nano 33 IoT Board topology top Ref.

I C peripherals (IMU and Crypto). NOTE: As opposed to other Arduino Nano boards, pins A4 and A5 have an internal pull up and default to be used as an I C Bus so usage as analog inputs is not recommended. -
Page 8: Imu
The board has an embedded 6-axis IMU which can be used to measure board orientation (by checking the gravity acceleration vector orientation) or to measure shocks, vibration, acceleration and rotation speed. Source code for the Arduino Library that supports the IMU is available [15] 3.6 Power Tree... -
