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.

– 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.

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 ...

The Arduino Nano and Raspberry Pi Pico support different input voltages, so they also use different power sources. However, they can both be powered with a 5V supply via their onboard USB ports.

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 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.
