         N88XX  single-sided Simulator Module

                                             FRONT                           BACK

The N88XX simulator module is slightly larger in physical size (0.375" x 0.375") as compared to our original N80XX, .NLA80XX, NLD80XX & L80XX simulator modules (0.310" x 0.310").

The reason for this difference is that we have placed all of the components on the front side of the board and have replace the through-hole solder points with top-surface solder pads for wire connections.. This allows the back of the board to be electrically "blank" for situations that require direct mounting to modeling surfaces without concern about electrical shorting issues or flat surface requirements.

The N88XX series has the same on-board 5-volt DC precision regulator for output voltages and supports a DC input voltage range of 5.6-18 volts. The on-board microcontroller has three programmable outputs and one input for control functions just like ourN80XX series. It also has on-board DC polarity protection which can be usefull for model railroaders in Analog applications that require lighting effects that operate in forward track polarity but not in reverse.

Additionally, we have provided a front surface placement for a third current limiting resistor and two pair of solder-jumper pad sets for configuring that resistor's connection to either –DC (ground) or +DC (+5-volts).

This N88XX series can be programmed for any of our existing lighting effects.
