Like the Nano, the Micro's size and male pin headers make it perfect for prototyping with a breadboard. However, Arduino also offers this board without headers pre-soldered.

The board is built around an ATtiny3217 and has almost all of the Nano’s features, like a USB port, reset button, built-in LEDs, 5 V regulator, and preloaded bootloader.

Arduino Maker Nano RP2040 “Slightly shorter than a Pico, this board has 30 pre-soldered pins, all helpfully labelled on the silkscreen.

Arduino enthusiasts and makers searching for a new project to keep them busy this weekend may be interested in a new DIY Arduino Nano multimeter created by YouTuber Electronoobs.

Arduino has introduced a Nano shaped board with a Wi-Fi and Bluetooth LE capable Espressif’s ESP32-S3 microcontroller, supporting it with the Arduino IDE and MicroPython. “Beginners can explore in an ...

The Arduino Nano and Uno are equipped with very similar processors (the chip that essentially serves as the brain of the board). The Nano features an ATmega328, while the Uno sports an ATmega328P.
