The Gravity Digital RGB LED Module is a fantastic cascading single RGB LED module that works great with RGB LED strips. Its Gravity interface offers a sleek way to connect with most mainstream controllers like Arduino, micro:bit, Firebeetle Series, LattePanda, and Raspberry Pi, along with various DFRobot IO expansion shields. Unlike traditional RGB LED modules that need three control signal pins per LED, this module only requires one signal pin for all cascaded LEDs. This unique design results in extremely low power consumption per meter compared to traditional strips. You can cascade over 100 modules, reaching lengths of several tens of meters, with a power requirement of just 5V 2A. It also makes it super easy and flexible to set the length of your RGB LED strip without cutting or soldering each LED. The module uses the same high - brightness RGB LEDs as traditional strips, ensuring excellent display performance and full compatibility with existing driving circuits and programs. So, you can easily switch your existing programs from LED strips to this module string. Have a blast creating cool effects like flashing, rainbows, and even showing letters, pictures, or animations with this small but powerful RGB LED module. Key features include excellent display with high - quality WS2812 RGB LEDs, extremely long cascading lengths with low power consumption per unit length, high compatibility with 3.3V/5V controllers and RGB LED strip drivers or programs, and a standard connector for easy setup without cutting or soldering. Applications range from holiday decorations to signal indicators. Specifications are as follows: LED Type is WS2812 RGB 5050 LED, Input Voltage is 3.3V - 5.5V, Maximum Current is 48mA, Quiescent Current is 0.7mA, Interface is Gravity 3P Digital, and Dimension is 30.0mm*22.0mm (1.18*0.87 in). You can find more information in the product wiki and other related documents.
Using the Gravity Digital RGB LED Module is quite easy. First, connect the module to your chosen controller (like Arduino or Raspberry Pi) through the Gravity 3P Digital interface. Make sure the input voltage is within the 3.3V - 5.5V range. You can cascade multiple modules together to create longer LED strips as needed. For programming, since it's compatible with RGB LED strip drivers and programs, you can use existing code with just minor adjustments. When creating effects, you can use programming to make the LEDs flash, show rainbows, or display letters and pictures. As for maintenance, keep the module away from moisture and high - temperature environments. If you notice any LED not working properly, check the connections first. Also, be careful not to exceed the maximum current of 48mA to avoid damaging the module. Overall, this module is a great choice for adding some cool lighting effects to your projects.
