The aptly named “Nano DIP,” which at 33 mm x 10 mm — about the same size as the ATmega328 on the Arduino Uno — will tickle the miniaturization fans out there.

– 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.

The Arduino Nano 33 BLE Rev2 is a significant leap forward in the world of microcontroller boards, designed to empower a diverse array of projects with its advanced capabilities.

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.

The power of Espressif’s ESP32-S3 meets Arduino’s unmatched customer experience, documentation and community — all in the compact form factor of the Nano. Provides support for both ...
