It breaks out all I\/O pins into organized 3-pin headers, enabling quick and solderless connections for sensors, servos, and modules. Ideal for rapid prototyping, it simplifies wiring and reduces clutter in your projects.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\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\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003e5V DC (via Arduino Uno)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDigital I\/O Pins\u003c\/td\u003e\n\u003ctd\u003e14 (0-13) broken out to 3-pin headers\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eAnalog Input Pins\u003c\/td\u003e\n\u003ctd\u003e6 (A0-A5) broken out to 3-pin headers\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCommunication Interfaces\u003c\/td\u003e\n\u003ctd\u003eUART, I2C, SPI (via dedicated headers)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eServo Headers\u003c\/td\u003e\n\u003ctd\u003e2 dedicated 3-pin servo ports\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eAdditional Features\u003c\/td\u003e\n\u003ctd\u003eBluetooth\/APC220 module interface, power LED, reset button\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e55mm x 53mm (approx.)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-obstacle-avoiding-robot\"\u003eObstacle-avoiding robot with ultrasonic and IR sensors\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-indoor-weather-station\"\u003eWeather station measuring temperature, humidity, and pressure\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eHome automation system with relays and motion detectors\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-line-following-robot\"\u003eLine-following robot for beginner robotics competitions\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis shield is designed for the Arduino Uno R3 form factor. It can also work with Arduino Mega 2560 if aligned correctly, but check pin mapping for compatibility. All pins operate at 5V logic; use level shifters for 3.3V sensors if needed. Common pairings include HC-SR04 ultrasonic sensors, DHT11\/DHT22 temperature sensors, and servo motors.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eSimply align the male headers with your Arduino Uno and press firmly. All signal, power, and ground connections are pre-routed to the 3-pin headers; no additional wiring is needed for most sensors. If using high-current loads like multiple servos, power them through the shield’s separate power input header rather than the Arduino’s 5V pin.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs this shield compatible with the Arduino Mega?\u003c\/summary\u003e\u003cp\u003eYes, it can physically stack on the Mega, but some pins (like I2C) are on different locations. You will need to adjust the wiring in your code accordingly.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan I use this shield with a Raspberry Pi?\u003c\/summary\u003e\u003cp\u003eNo, this shield is designed for 5V Arduino boards and does not match the Raspberry Pi’s GPIO header or 3.3V logic. You would need a separate adapter.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eDo I need to solder anything?\u003c\/summary\u003e\u003cp\u003eThe shield comes with pre-soldered headers for stacking onto the Arduino. The sensor pins are typically male headers, so you will connect sensors using jumper wires without soldering.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
