The Pac-Drive circuit board

Is a driver board for devices such as LEDs, solenoids, lamps etc

It will drive up to 16 standard LEDs with no additional power. Up to 4 boards can be used (more by request). Different IDs available. 500mA per channel 500mA total current without external power supply. Higher current draw will require additional power. 5 volt outputs without external power supply. Up to 48 volt outputs with external power supply. Open-Source software. No driver required. Downloadable example VB application. C++ code on request. Support as a LED driver for several MAME front-ends (MaLa, GameEX etc).
