Description
A hobbyist or educator lot containing four (4) Uno R3 development microcontroller boards based on the ATmega328P processor. These open-source electronics platforms are the industry standard for prototyping, DIY robotics, sensor integration, and coding education.
The lot includes a mix of official Italian-made boards and a premium third-party compatible alternative:
-
Official Arduino Uno R3 (3 Units): Original flagship revision boards featuring the distinct teal solder mask, crisp factory branding, and “Made in Italy” or “arduino.cc” text printed on the PCB. Includes the socketed DIP-package ATmega328P-PU microcontroller chip.
-
SainSmart Uno R3 (1 Unit): A highly regarded, premium 100% hardware-compatible drop-in replacement board featuring a deep blue solder mask, identical pin headers, and matching component layout for plug-and-play compatibility with standard shields and the Arduino IDE.
-
Form Factor & Connectors: All boards feature standard female pin header rails, standard USB Type-B interface ports, and a barrel jack connector for external DC power supply input.
-
Condition: Pre-owned, clean physical condition with header pins straight and intact. Connectors show minor structural patina from storage, typical for bench-tested components. Sold as a bulk hobbyist lot.
