This small, robust and powerful board has WiFi and Bluetooth connectivity that combined with its low power architecture makes it a practical and cost effective solution for your connected projects.
Arduino Nano33 IoT is fully compatible with the Arduino IoT Cloud and supports full TLS secure transport: the ATECC608A crypto-chip stores the cryptographic keys in hardware, offering a very high level of security for this class of products. The integration with the Arduino IoT Cloud offers also a very efficient way of setting up online dashboards with little coding and minimal effort.
In the same iconic size of the Arduino Nano, the Arduino Nano 33 IoT hosts an Arm Cortex-M0+ SAMD21 processor, a WiFi and Bluetooth module based on ESP32, a 6-axis Inertial Measurement Unit (IMU) and a crypto chip which can securely store certificates and pre shared keys.
The board can either be used in a breadboard (when mounting pin headers), or as a SMT module, directly soldering it via the castellated pads.
- The board is based on the SAMD21G18A microcontroller
- Clock frequency up to 48MHz
- Flash 256KB
- SRAM 32KB
- WiFi connectivity
- Bluetooth connectivity
- Fully compatible with Arduino IoT Cloud
- Same size as Arduino Nano
- Arduino type: Nano 33 IoT
Please note: The Arduino Nano 33 IoT 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.
To avoid such risk with existing projects, where you should be able to pull out a Nano and replace it with the new Nano 33 IoT, the 5V pin on the header, positioned between RST and A7 is not connected as a default factory setting. This means that if you have a design that takes 5V from that pin, it won't work immediately. This is a precaution put in place to draw attention to the 3.3V compliance on digital and analog inputs.
