If you have 32 74HC595, you can have two colors, which can show red, green and yellow colors.It depends on how many boards you have and what you want to control with serial ports or network ports. Serial port cheaper. The net mouth is the cheapest 140 yuan.
Are you the only one?. The 32 dot matrix is a unit board.Depends on how much you 74HC595 chip unit board, 16 monochrome, can do text screen for onbon t-card on the line, to 50 yuan. Software works well.
From the story of this screen, you should guess is the interior of the screen, usually can use the adapter plate HUB08, the controller can choose the high market share of the Shanghai spirit, onbon letter, equal etc.. You can also choose some other brands. As long as the parameters meet the requirements.
