Pixblaster MS1 Controller Software Led Edit

The Pixblasters MS1 video LED controller connects to any computer and any operating system as an ordinary monitor to display the user-selected portion of the monitor image on up to 16,384 RGB LEDs at 60 frames per second (FPS). Multiple MS1 controllers can be easily chained to drive immense video displays built of hundreds of thousands of perfectly synchronized LEDs1. The Pixblasters MS1 displays any visual content with absolutely no programming required and with no burden on the driving computer that is free to run digital signage players, media players, and other software at the full speed. The LED displays controlled by the Pixblasters MS1 can be remotely managed anywhere in the world by virtually any digital signage software.


  • Includes the DVI® compatible video input with the on-board EDID flash and accepts the standard monitor cable

  • Currently supports popular WS2811, WS2812, WS2812B, and SK6812 LED driver chips (3-wire interface)

  • Support for APA102, SK9822 , HD107… and other APA102-like LED driver chips planned for 1Q21 (4 – wire interface)
  • Supports different video input resolutions (max. 720p – 1280×720@60) and the RGB666 (256K colors) color forma

  • Drives up to 16,384 LEDs through 32 digital outputs that drive up to 512 LEDs each

  • Supports wide range of output resolutions (H x V):  512 x 32 (native), 256 x 64, 128 x 128, 180 x 96 and others

  • Integrates video input cropping and mirroring, multiple lines per output mode and LED gamma corrections

  • Displays any graphics and video content – no limits on font types, animations, image and movie formats…

  • Chained controllers can drive more than 200,0001 of perfectly synchronized LEDs arranged in giant video displays

  • Maximum LED display frame rate (60 FPS for WS2812B) is not affected by a number of controllers and attached LEDs

  • Use common UTP cables (Ethernet) for video and control links between chained controllers

  • Validated with different computers and different OSes: Raspberry Pi, PC, media boxes, phones and tablets

  • Can be remotely controlled anywhere in the world through the network interfaces of the driving computer

  • The driving computer is free of LED controls and the size of the LED display does not influence its performance

  • The driving computer can run digital signage players, media players, web kiosk applications, custom software, etc.

  • Display content can be designed and remotely administrated by any Digital Signage Software2

  • On-board Microchip PIC18F26J50 microcontroller enables updates and permanently stores the display configuration

  • Fully configurable through a configuration menu on the PC connected via the USB cable

  • New features can be added to deployed controllers through a simple firmware upgrade procedure

  • Single MS1 can be easily configured as a master or as a slave controller by on-board DIP switches

  • Snap-action connectors enable easy wiring of the complete display with no need for any soldering

  • The LED power supplies need to be wired separately to enable power and current requirements of giant LED displays

  • Board dimensions: 95 x 100 mm
