Product Reference Manual
SKU: ABX00027
Description
Nano 33 IoT is a miniature sized module containing a Cortex M0+ SAMD21 processor, a WiFi+BT 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.
Target areas:
Maker, enhancements, basic IoT application scenarios
