Nixtrainz, NTZ5, HO Scale, Decoder Buddy Motherboard for 21 Pin Decoder, Version 5

The Decoder Buddy V5 was developed for the 12 output decoders and include a couple added features.

This mother board does not include the 21-Pin Decoder.

This mother board requires soldering.

This printed circuit board is NOT INTENDED FOR USE IN A DC SYSTEM.  However, if the decoder you are using supports DC operation it should work.

The V5 and V5B come with standard 2.2K resistors onboard.

I can substitute / supply custom specified resistors for function outputs.  These may be requested by the email link.

The mother board includes

• One 21 Pin Decoder receptacle
• Two pairs of track input pads
• One pair of motor input pads
• One set of stay alive pads (U+, GND on the V5.  The V5B has the “W” pad for a Power Pack)
• Two pairs of speaker pads in parallel by side
• 12 lighting outputs on a separable “small connector board”
• Lighting outputs A11 and A12 are replicated on the “motherboard”

Resistors for use with LED lighting. The “0” ohm resistors accommodate previously installed LEDs with resistors in line and “12-volt LEDs”.  It is IMPORTANT to realize that resistors must be used when LEDs are connected to the lighting outputs of the custom “0” Ohm boards!!!
