The LED dot matrix display module using AT89S52 microcontroller. It can display graphics, animation and English characters, etc. display has a static, horizontal scrolling, vertical scrolling and page display.
Single module controls 12 drives (up to 24 can be controlled) 8X8 dot matrix, a total of 16X48 dot matrix (or 32X48 dot matrix), is a single block MAX7219 (or PS7219, HD7279, ZLG7289 and 8279 and similar LED display driver module) of 12 times (or 24 times)! Can " cascade" approach the composition of arbitrary large dot matrix display. Show the effective power of small, and the MAX7219 circuit than lower cost.
Can help you better learning microcontroller.
