These are the tiniest NeoPixel breakouts you can find! Add these super - bright RGB + White pixels to your project. Measuring just 9.1mm x 9.1mm, these small PCBs have two sets of three pads on the back for easy wire soldering. The ultra - bright LEDs come with a built - in constant - current driver right in the LED package. The pixels are chainable, allowing you to control as many LEDs as you want with just 1 pin/wire. They offer full 32 - bit color ability (24 bits for RGB and 8 bits for white), with the controller chip handling PWM. Because the LEDs are extremely bright, you need less current and power to achieve the desired effects. The constant - current driver ensures stable performance even if your battery power fluctuates. The NeoPixel is unique, with one half being the familiar RGB and the other half a white LED with yellow phosphor. When lit, they're incredibly bright! You can control each channel with 8 - bit PWM (8 x 4 channels = 32 - bit color overall), making them perfect for adding lots of colorful and warm white dots to your project. Note that these are RGBW pixels, so make sure your NeoPixel controller is set up for RGBW, not the standard RGB. Each pixel can draw up to ~70mA at full - brightness white. An Arduino can drive up to 350 pixels at 30 FPS. You can space them up to 6' apart using ribbon cable, but beyond that, you may encounter power issues and data corruption. Each order includes 10 individually controllable pixel buttons. We have a tutorial for wiring, power usage calculations, and example code. Remember, you'll need a NeoPixel library with RGBW support, which isn't always available. Our Adafruit NeoPixel library supports RGBW, but other libraries may need some adjustments. Also, the blue LED has a bit of white light mix due to its proximity to the white phosphor.
Using these NeoPixel RGBW Mini Button PCBs is easy. First, solder wires to the two sets of three pads on the back of each PCB. Then, connect them in a chain as they are chainable, and you only need one pin or wire to control multiple LEDs. Make sure your NeoPixel controller is set to RGBW mode before use. When it comes to power, each pixel can draw up to about 70mA at full - brightness white. An Arduino can handle up to 350 pixels at 30 FPS, so plan your project accordingly. You can use ribbon cable to space the pixels up to 6 feet apart. However, if you go beyond this distance, you might face power and data issues. For programming, you'll need a NeoPixel library with RGBW support. Our Adafruit NeoPixel library is a good choice, but if you use other libraries, you may need to make some tweaks. Maintenance is simple. Keep the PCBs clean and dry. Avoid exposing them to extreme temperatures or moisture. If you notice any issues with color or brightness, double - check your wiring and the settings of your NeoPixel controller.
