… shield compatibility in favor of a miniaturized footprint (48x18 mm) and lower cost. The Nano 33 IoT is built around the ESP32, which is primarily aimed at WiFi but supports Bluetooth® as well, although with higher power consumption than the Nano 33 BLE. The Arduino Nano 33 IoT is available in pre-order in the Arduino online store with headers (estimate shipping date: end of July 2019) or without headers mounted (estimated shipping date: mid-June 2019).
