What is TM1814 addressable LED strip light?
TM1814 LED is a 4-channel constant-current adjustable driver IC, integrates a single-wire digital interface, data latch, LED constant current drive and other circuits;which can be input by MCU (SPI controller) with a set of constant current setting and PWM (digital-to-analog conversion, 256-level brightness adjustment) setting data to TM1814 LED chip to achieve a variety of dynamic color chasing effects. The VDD pin integrates a 5V voltage regulator tube with stable performance.
The LED light strip adopts return-to-one code (digital signal adopts baseband transmission) communication mode, single-wire serial cascade interface, built-in RC oscillation and clock synchronization according to the data line signal, after receiving the 32bit data of this unit, it can automatically follow up and the data is regenerated and sent to the next stage through the data output terminal; the signal does not appear to be distorted or attenuated as the cascade becomes farther.
It has four PWM output ports OUTR/OUTG/OUTB/OUTW to stably output signals with different duty cycles, it can display RGBW full-color lighting effects, support DC12/24V low voltage input, and can be used with Raspberrypi/Arduino UNO development board to achieve precise color control to meet the needs of short-distance lighting.
