Arduino Uno R3 Development Board with USB-A to USB-B Data Cable

This item is an Arduino Uno R3 development board paired with a blue USB-A to USB-B data cable. The Arduino board features a vibrant blue FR4 printed circuit board (PCB) which serves as the foundation for its electronic components. It is rectangular in shape, approximately 2.7 inches by 2.1 inches, and boasts a standard layout for Arduino Uno boards, including a central ATmega microcontroller (specifically a surface-mounted component, not a removable DIP package, as per context). Key components visible include rows of female header pins for digital and analog I/O, a USB-B port for programming and power, a DC power jack, a reset button, and various surface-mounted resistors, capacitors, and voltage regulators. The silkscreen printing on the board is crisp and legible, indicating pin functions and component identifiers. The board appears to be in excellent condition with no visible damage, corrosion, or signs of heavy use. The accompanying data cable is a translucent blue, woven-sheathed USB-A to USB-B cable, appearing significantly longer than standard Arduino data cables, possibly extending to 6 feet or more. Both USB connectors are clear plastic with metallic contacts and show minimal, if any, wear. There are no obvious manufacturer's markings on the cable itself beyond the standard USB logo. This R3 revision, identifiable from its ATmega16U2 (or similar) USB-to-serial converter package near the USB-B port and its overall layout, represents a common and widely utilized micro-controller platform. The presence of the SMC ATMEGA chip on the mainboard, rather than a through-hole, socketed component, confirms its R3 or later revision status, and depending on the specific chip (e.g., ATmega328P), it aligns with standard Arduino Uno R3 specifications. The build quality of both the board and the cable appears standard for consumer electronics of this type, indicating a functional and ready-to-use set.
