SK6812 5050 RGBW Stick Full Color LED with Integrated Drivers Development Board Lamp Panel Module

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 can
