Features: 1. This is the cool white RGBW version.
2. The board is a split type, half of which is the RGB that you are familiar with and favorite, and the other half is a white LED with yellow phosphor. They will light up abnormally after lighting, and can be controlled by 8-bit PWM per channel (8 x 4 channels = total 32-bit color).
3. We assemble eight tiny 5050 (5mm x 5mm) smart RGBW LEDs on a beautiful circular PCB with mounting holes and linkable design, you can only use one microcontroller pin to control as many links as possible Together! Since the driver chip is located inside the LED, each LED can be addressed. Each driver has an 18mA constant current driver, so even if the voltage changes, the color will be very consistent, and no external choke resistor is required to make the design slimmer. Use 5VDC to power the entire device (4-7V work).
4. The 800 KHz protocol is used, so a specific timing is required. The PWM frequency is about 400 Hz, which works well, but it is worth noting if the LED is moving. In contrast, DotStars has a PWM frequency of 20 KHz, so even when you move the LED around, you will not see pixelation and the mixing is very smooth. (If it can be used, we recommend DotStars)
5. These LEDs are linkable by connecting the output of one jewelry to the input of another jewelry. Only one data line has a very timing-specific protocol. Since this protocol is very sensitive to timing, it requires a real-time microcontroller, such as AVR, PIC, mbed, etc. It cannot be used with Linux-based microcomputers or interpretative microcontrollers such as netduino or Basic Stamp. We have written an excellent library to support these pixels! Since it requires manual debugging assembly, it is only suitable for the AVR kernel, but others may have ported this chip driver code, so please search around Google. Requires 8MHz or faster processor.
6. A single circular board with 7 individually addressable RGBW LEDs for assembly and testing.
