– Arduino Nano 33 IoT – small, secure, and Internet-connected. (Pre-order here with headers or here without headers) – Arduino Nano 33 BLE – small, low-power, and Bluetooth-connected.

The Nano is a nice and modest update to the older Arduino Micro/Nano boards. The Arduino Nano 33 IOT has an ESP32 onboard (WiFi + Bluetooth) and crypto onboard with the uBlox NINA-W10.

The Nano ESP32 supports both Micropython and Arduino programming languages, providing a clear path for those already familiar with one platform to easily switch back and forth as needed.

Features and Benefits. The Arduino Nano ESP32 presents a unique blend of features that make it the ideal microcontroller for an array of IoT applications, from home automation and gaming to education.

The Nano 33 IOT costs $18, offering Wi-Fi and Bluetooth connectivity. It's powered by the SAMD21G18A microcontroller, runs up to 48 MHz with 256KB of flash and 32KB of RAM.
