Elecrow UNO R3 Board ATmega328P ATMEGA16U2 with USB Cable for Arduino

An Arduino UNO R3 compatible development board from Elecrow, built around the ATmega328P microcontroller with an ATmega16U2 for USB communication. Fully compatible with the Arduino IDE and the vast ecosystem of Arduino shields, libraries, and tutorials — a great starting point for learning electronics and programming.

The ATmega16U2 USB interface provides reliable, native USB communication (no third-party drivers needed on most systems). A USB cable is included so you can start programming right out of the box.
