The MR-218DW is a versatile LED sub-controller that supports a wide range of addressable LED chips and strip types. Matching with the master controller MR-BF12B, it offers multiple control options, including smartphone applications, remote controls, and DMX512-compliant control systems.

1. The controller has 8 output ports, each port can carry up to 170/512/768 pixels(Different pixels for different
2. The controller port outputs two kinds of signal protocol: (1)DMX512/1990 international standard protocol and DMX512 extended protocol; (2)SPI/TTL serial protocol.
3. The controller output port provides three protections to ensure that the controller output port is not burned out in the case of a short circuit or reverse connection in the controlled lamp.
4. Controller ID automatic/manual numbering function, which can be numbered together with multiple controllers, or individual controller numbers.

The T790K supports input voltages of 5V to 24V and can control up to 4096 pixels. Matching with XB-Z2 master controller, it supports multiple chip types and offers a range of control methods, including smartphone applications and DMX512 compliant systems. 

  1. Support 8 output ports, each can carry a maximum of 1024 pixels (TTL and DMX512).
  2. The port outputs two types of signal protocols: ①DMX512/1990 international standard protocol and DMX512 extension protocol; ② SPI/TTL serial port protocol.
  3. Load DMX512 lamps, with the output rate of 250K/500K/750Kbs.
  4. When controller with Madrix software, each port can load 1/2/3/4/5/6 Univ of lamps (one Univ = 170 point light sources).

LED Sub-Controller Applications

Why Need Addressable LED Sub Controllers?

Table of Contents


Addressable pixel LED sub-controllers are essential components in the world of LED lighting, as they allow for fine-grained control over individual LEDs or groups of LEDs in a strip. These controllers make it possible to create stunning visual effects, synchronize lighting with music, and incorporate interactive elements into your lighting projects. In this article, we will discuss two popular addressable pixel LED sub-controllers: the MR-218DW and the T-790K.

Working Mechanism of Addressable Pixel LED Sub-Controllers

Addressable pixel LED sub-controllers work by receiving control signals from a master controller or control device and translating those signals into instructions for the individual LEDs on a strip. This allows for precise control of color, brightness, and timing for each LED, enabling complex lighting patterns and effects.

Benefits of Using Addressable LED Sub-Controllers

Addressable LED sub-controllers provide numerous benefits, including:

Setting Up an Addressable LED System

Choosing the Right Sub-Controller

Selecting the appropriate sub-controller for your addressable LED strip is crucial for achieving the desired lighting effects. Consider factors such as the type of addressable LED strip, the number of pixels, and the control method when making your decision.

Connecting the Components

Properly connecting the components is essential for the proper functioning of your addressable LED system. This includes connecting the sub-controller to the LED strip, power supply, and master controller or control device.

Configuring the System

After connecting the components, configure the system by selecting the appropriate communication protocol, setting the pixel count, and adjusting any other necessary settings.

Programming Addressable LED Strips
