To control LED signals with slow dimming feature which connects directly to the MGV50.
Selectable for common cathode or anode signals. Thus depending on how leds in one railroad sign are connected together.

The setup of this unit is so simple, that many possibilities are possible. Complex sign combinations can be made, without having to ask Rocrail team for special sign situations. Even feed-back information to Loconet would be an option.

All this is simply established by changing the simple software in the processor.

I will be glad to assist in any (software)wishes for making this unit suitable to the desired situation.

To create software for this processor, a very fast and solid basic compiler from www.oshonsoft.com is used.

To make things easy when connecting Leds to the GCA86, resistors are already on the pcboard, so leds can be directly wired to it. (sse picture).

This board is a D.I.Y. project. No boards available.
