Made for a major gaming machine manufacturer, these boards were NOT CHEAP ! Built on a fibre glass pcb (much easier if you want to de-solder the parts) the board consists of 14 large green 7 segment LED displays, type # LA2521, 2 MM5450N (more info below) driver IC's, and other discreet transistors & components. The unit was designed to display scores etc, but its function could be made to show time & date, custom chess / game timers or even dessolder the BRAND NEW parts, anything a bit of ingenuity could imagine! A full circuit is available by clicking on the button below. Easily interfaced to a PIC etc.
All the inputs and outputs terminate on a standard 20 way header (2 x10 male) mounted to the rear.
