Arduino Nano 33 IoT Development Board, ARM Cortex-M0+ CPU / Headers - 

Arduino Nano 33 IoT with headers is a small, robust and powerful board has Wi-Fi and Bluetooth connectivity. Combined with its low power architecture makes it a practical and cost effective solution for connected projects. The integration with the Arduino IoT Cloud offers also a very efficient way of setting up online dashboards with little coding and minimal effort. 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 with headers mounted. It is the easiest and cheapest point of entry to enhance existing devices (and creating new ones) to be part of the IoT and designing pico-network applications.
