{"title":"RGB LCD Shield Kit w/ 16x2 Character Display - Only 2 pins used! [POSITIVE DISPLAY]","handle":"rgb-lcd-shield-kit-w-16x2-character-display-only-2-pins-used-positive-display","url":"/products/rgb-lcd-shield-kit-w-16x2-character-display-only-2-pins-used-positive-display","description":"This Arduino shield kit combines a 16×2 RGB character LCD with five navigation buttons, all controlled over I2C using just two pins (Analog 4 and 5). An on-board I2C port expander handles the LCD, RGB backlight, and keypad inputs, leaving your remaining pins free for sensors and other peripherals — and the I2C bus can still be shared with other devices.\n\nThe five directional buttons (up, down, left, right, select) provide a built-in user interface for standalone projects without needing a computer. This is the positive display version (black text on RGB backlight).\n\nKey Features\n\n\nI2C Control – LCD, backlight, and buttons all managed via two I2C pins\n\n16×2 RGB LCD Included – Positive display (black on RGB) with 7 backlight colours (red, yellow, green, teal, blue, violet, white) plus off\n\n5 Navigation Buttons – Up, down, left, right, and select with automatic debouncing\n\nShared I2C Bus – Other I2C devices (sensors, RTCs, etc.) can share the bus\n\nArduino Library – Drop-in replacement for LiquidCrystal with built-in keypad support\n\n\nCompatibility\n\n\nArduino Uno, Duemilanove, Diecimila – Direct plug-in\n\nArduino Mega R3 – Works with the extra SDA/SCL pins\n\nEarlier Mega – Requires two wires soldered from the shield I2C pins to Digital 20 and 21\n\n\nIdeal For\n\nStandalone projects with on-device user interfaces\nMenu-driven Arduino applications\nSensor readout displays\nLearning to solder (beginner-friendly kit)\n\n\nPackage Contents\n\n1× PCB shield board\n1× 16×2 RGB positive LCD\n5× Navigation buttons\nHeaders and all required components\n\n\n\nNote: This is a soldering kit requiring assembly (~30 minutes). The I2C expander does not support PWM, so backlight colours are on/off only (7 colours plus off — no smooth colour mixing).\n\n\nResources\n\nAssembly Instructions and Tutorial\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":13309,"title":"Default Title","sku":"AF-716","price":52.87,"on_sale":false,"in_stock":true,"available_quantity":36,"option1":"Default Title"}]}
