ARDUINO UNO R3 — A000066 Brand New, Sealed Original Retail Packaging, Made in most popular Arduino board, and the perfect choice for anyone starting out with microcontrollers, embedded systems, or prototyping. Powered by the ATmega328P with the ATmega16U2 USB — Brand New, Sealed Retail is an official Arduino Uno R3 (A000066) in its original sealed retail packaging. Factory sealed, never opened. You\'ll receive the box exactly as it shipped from Arduino SA in Italy, with the official branding and \"DESIGNED AND ASSEMBLED IN ITALY\" marking clearly visible on the box. This is NOT a clone, NOT a compatible, NOT a \"functionally equivalent\" board. This is the original THIS LISTING MATTERS — Arduino Uno market is flooded with Chinese clones priced at $8–15. Clones often work, but they lack the quality control, long-term reliability, proper USB interface chip (most clones substitute CH340 for the ATmega16U2), and official Arduino Foundation support of a genuine board.
