– 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 electronics are straightforward, with the complete parts list consisting of an Arduino Nano 33 IoT device connected to a pair of RGB LEDs and 50 Ohm resistors.

This consists of different variations of the Nano, such as the Nano ESP32, Nano 33 BLE, and Nano 33 IoT. The Arduino Nano itself is the most basic and oldest of the group, and just like its many ...

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 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.

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.

Despite the differences in size and microcontroller, the Arduino Nano and Micro share some similar pinout configurations. They both have two GND pins, two reset pins, one AREF pin, and three power ...
