NixTrainz Decoder Buddy Mini - NTZ3 motherboard for 21 Pin decoders (Scale=HO) #NIX-DecoderBuddyMini

The NixTrainz NTZ3 Mini Decoder Buddy is a specialized motherboard designed for 21 Pin decoders in HO scale train models. It's ideal for smaller steam and diesel train applications, and has also caught the interest of HOn3 and S - Gauge enthusiasts. This motherboard doesn't come with the 21 Pin Decoder and requires soldering. It's important to note that it's not for use in a DC system. Included with the board are four axial resistors (2.2K) for LEDs, which can be mounted remotely inline. Custom - specified resistors for function outputs can be requested via email. The motherboard features a 21 Pin Decoder receptacle, two pairs of track input pads, one pair of motor input pads, one set of stay - alive pads, one pair of speaker pads, and resistors for LED lighting. Different resistors like 0 ohm, 750 ohm, or custom ones are also available for incandescent lamps. Remember, when connecting LEDs to the four lighting outputs, resistors must be used. Until the next batch, the Mini will be labeled Tiny, and the package picture shows the correct headlight outputs for locomotive direction.

Using the NixTrainz NTZ3 Mini Decoder Buddy is a great way to enhance your HO scale train. First, make sure you have all the necessary tools for soldering as the motherboard requires it. Since it doesn't come with the 21 Pin Decoder, you'll need to get one separately. When installing, connect the components to their respective pads: the decoder to the 21 Pin Decoder receptacle, use the track input pads for track connections, the motor input pads for the motor, and so on. For the LED lighting, don't forget to use the resistors. You can either use the included 2.2K axial resistors or request custom - specified ones. If you're using incandescent lamps, choose the appropriate resistors. Always remember that this motherboard is not for DC systems. When it comes to maintenance, keep it clean and dry. Check the soldered connections regularly to make sure they're secure. And if you need custom resistors, just use the email link provided.
