Arduino Nano 33 IoT with headers

Description of product


Arduino Nano 33 IoT combines WiFi and Bluetooth® connectivity with a low power architecture for a cost-effective connected project solution. The Arduino Nano 33 IoT is fully compatible with the Arduino IoT Cloud. The device supports full TLS secure transport. The ATECC608A cryptochip stores the cryptographic keys in hardware, offering a very high level of security.

Integration with the Arduino IoT Cloud allows for an efficient way of setting up online dashboards with little coding and minimal effort. The Nano 33 is the same size of the Arduino Nano and hosts an Arm Cortex-M0+ SAMD21 processor, a WiFi and Bluetooth module based on ESP32. The Nano 33 also features a 6 axis Inertial Measurement Unit (IMU) and a crypto chip which can securely store certificates and pre shared keys. Use the board as a breadboard (when mounting pin headers), or SMT module, directly soldering it via the castellated pads.
