What is TM1812 LED strip light?
TM1812 is a 12-channel LED drive control dedicated circuit (16-pin IC, 4 OUTR/OUTG/OUTB output interfaces), which integrates MCU digital interface, data latch, LED high voltage drive and other circuits. The peripheral MCU controls the individual brightness of the chip, and the cascades control to achieve color dot matrix light control of addressable LED strip light.
Data transmission adopts single-wire serial cascade interface (each group of addressable LEDs is designed in series and each group of cuttable units is designed in parallel), built-in power-on reset, receiving 24bit data transmitted from DIN side, OUTR/OUTG/OUTB receiving data and sending signals with different duty cycle. Built-in RC oscillation and clock synchronization, according to the signal on the data line, after receiving the data of this unit can automatically send the subsequent data shaping through the data output to the next level, the signal does not become distorted or attenuated as the cascade becomes farther away (the maximum data transmission speed is 800Kps, there is no flicker phenomenon).
At the same time, we provide DC12V addressable LED strips, single LED can be cut, 5 meters separately powered, and 10 meters powered at both ends. You can customize the length, waterproof level, luminous color, and LED arrangement quantity of LED strips for your indoor and outdoor lighting projects; it can be used with Raspberrypi/Arduino UNO development board or Dream Color LED controller to achieve precise luminous color and mode control.
