3-Pack UNO R3 ATmega328P Board USB-C, ENIG Gold

INDUSTRY-STANDARD ATMEGA328P MICROCONTROLLER Powered by the Microchip ATmega328P running at 16 MHz with 32KB Flash, 2KB SRAM, and 1KB EEPROM. Drop-in replacement for the UNO R3 with identical pin layout - your existing code, libraries, and shields work out of the box. Suitable for learning embedded programming, prototyping IoT devices, and building robotics projects. BLACK GOLD EDITION - ENIG GOLD-PLATED FINISH Three boards with deep black solder mask and ENIG (Electroless Nickel Immersion Gold) plating, compared to the HASL finish used on many boards. Good solderability and oxidation resistance. Lead-free RoHS-compliant manufacturing. MODERN USB TYPE-C CONNECTIVITY Replaces the Type-B port with a reversible USB Type-C port for programming and power delivery. Plug in either way, using the same cable type as a phone or laptop. Includes one USB Type-C cable. PRE-SOLDERED HEADERS & STANDARD PINOUT Ships with pre-soldered headers and 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 UNO R3 - UNO R3 shields, sensor modules, and breadboard projects plug in directly with no adapters needed. C++ COMPATIBILITY Works with C++, PlatformIO, and other development environments. Compatible with online tutorials, libraries, and example projects. Three-board pack suits STEM classroom labs, multi-station workshops, and makers running several projects at once.
