Key Features

【INDUSTRY-STANDARD ATMEGA328P x 3】Three premium UNO R3 boards powered by Microchip ATmega328P at 16 MHz with 32KB Flash, 2KB SRAM, and 1KB EEPROM each. Drop-in replacements for original Arduino UNO R3 with identical pin layout - your existing code, libraries, and shields all work out of the box. Perfect for multi-board projects, classroom labs, or keeping spares on hand.
【BLACK GOLD EDITION - ENIG GOLD-PLATED FINISH】Striking deep black solder mask with industry-standard ENIG (Electroless Nickel Immersion Gold) plating instead of the cheaper HASL finish used by most clone boards. Superior solderability, excellent oxidation resistance, and a professional appearance that stands out on your bench. Lead-free RoHS-compliant manufacturing is safer to handle and built to last.
【USB TYPE-C WITH CABLE INCLUDED】Modern reversible USB Type-C port on every board for fast, hassle-free programming and power delivery. One USB Type-C cable included in the package - plug in and start coding immediately. No more digging through drawers for a Type-B printer cable.
【READY-TO-USE - PRE-SOLDERED HEADERS & STANDARD PINOUT】All three boards ship with pre-soldered headers and clearly silk-screened pin labels: 14 digital I/O pins (6 with PWM), 6 analog inputs, plus power rails (5V, 3.3V, GND, VIN). Identical footprint to the original Arduino UNO R3 - every Arduino shield, sensor module, and breadboard project plugs straight in.
【3-PACK VALUE BUNDLE - IDEAL FOR LABS & MULTI-BOARD PROJECTS】Three Black Gold Edition boards at a lower per-unit cost than buying singles. Perfect for parallel project development, classroom workstations (one per student), redundancy in production prototyping, or maker workshop teaching. Plug-and-play Arduino IDE compatibility with thousands of free tutorials and libraries.
