What is UCS1903 addressable LED strip light?
UCS1903 is a 3-channel LED driver control special circuit, built-in voltage regulator (256 levels of adjustable glow), dual RC oscillation (synchronous line signal transmission), power-on reset circuit (accept data from the DIN port), and internal integration of MCU digital interface, data latch, LED high-voltage driver circuit, through the peripheral MCU control to achieve the chip's individual glow ( luminous intensity), cascade control (each cutting unit individually controlled, single cutting unit damage does not affect the normal work of other cutting units, but serial single-line cascade, so the whole LED strip does not bright), to achieve addressable LED strip full-color lighting effect.
How do digital addressable LED work?
The data transmission adopts the unipolar return-to-zero code protocol communication mode. After the chip is powered on and reset, the DIN terminal accepts 24Bit data and stores it in the internal data latch to prepare for data transfer. Before receiving the RESET signal, OUTR/OUTG/OUTB sends signals with different duty cycles; when receiving the RESET signal, the chip re-accepts new data and uses automatic shaping forwarding technology to forward the data to the next chip; when 24us is received in the above low level RESET code, the chip outputs 24Bit PWM data to the OUTR/OUTG/OUTB pin. The data transmission speed is as high as 800Kps without flickering.
What is the feature of UCS1903 addressable LED strip light?
UCS1903 addressable LED strip supports DC5/12V low voltage input, DC5V, single LED can be cut, 5 meters powered at the two ends; DC12V, three LEDs can be cut, 10m powered at the two ends, with flexible design structure, matching Raspberrypi /Arduino UNO development board or dream color LED controller, using preset constant current mode matching to control the output current of the OUTR/OUTG/OUTB output port, and control the lighting effect and luminous mode of the LED strip. At the same time, we provide customized LED lights with length, width, density, and waterproof grade options to meet the diverse needs of customers for indoor and outdoor atmosphere lighting.
