Description
The DFRduino Nano USB Microcontroller V3.1 is a breadboard-friendly development board built around the robust Atmel ATmega328-20AU microcontroller. This compact board provides comparable functionality to the Arduino Diecimila, enhancing it with additional analog input pins and an onboard +5V AREF jumper, making it ideal for a wide range of embedded applications requiring a small footprint.
Designed for seamless integration into prototypes, the DFRduino Nano offers flexible power input options, including via its mini-B USB connection, an unregulated 6-20V external supply, or a regulated 5V external supply. The board intelligently selects the highest available voltage source, eliminating the need for manual power selection. Its optimized pin layout ensures compatibility and ease of use with standard breadboards and existing Arduino-compatible hardware.
