It eliminates the need for jumper wires on breadboards, making your projects more reliable and permanent. Perfect for prototyping and semi-permanent installations, it ensures connections stay firm even in high-vibration environments.\u003c\/p\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatibility\u003c\/td\u003e\n\u003ctd\u003eArduino Uno R3, Duemilanove, and clones with Uno pinout\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTerminal Type\u003c\/td\u003e\n\u003ctd\u003eScrew terminals (3.5mm pitch)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eI\/O Terminals\u003c\/td\u003e\n\u003ctd\u003e14 digital (D0-D13), 6 analog (A0-A5)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Terminals\u003c\/td\u003e\n\u003ctd\u003e5V, 3.3V, GND, Vin\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Terminal Rating\u003c\/td\u003e\n\u003ctd\u003e30V DC, 2A per terminal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e68mm x 53mm x 20mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHome automation system using relays and sensors\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/kit-sd-card-data-logger\"\u003eEnvironmental data logger with SD card and multiple sensors\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003eRobotics controller for motor drivers and servos\u003c\/li\u003e\n\u003cli\u003eEducational demonstration board for Arduino I\/O\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003cp\u003eDesigned for the Arduino Uno R3, this shield also fits the Duemilanove and most third-party boards with the standard Uno header layout. It will physically connect to an Arduino Mega 2560, but only the Uno-compatible pins (D0-D13, A0-A5) are broken out to terminals. The shield can be stacked with other shields if you use extended pin headers.\u003c\/p\u003e\u003ch2\u003eWiring Notes\u003c\/h2\u003e\u003cp\u003eSimply press the shield onto the Arduino Uno, ensuring all pins align. Insert wires into the screw terminals and tighten firmly. For power, use the Vin terminal if supplying voltage through the Arduino's barrel jack, or use the 5V\/GND terminals for logic-level peripherals. Do not exceed the current rating per terminal to avoid damage.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
