Decoder Buddy Mini and Tiny

The Decoder Buddy Mini and Tiny were developed to fit into smaller steam and diesel applications.  there has also been interest in HOn3 and S-Gauge applications.

Dimensions:

L=1.375

W=.65

H=.67 

 This mother board does not include the 21 Pin Decoder.

This mother board requires soldering.

These printed circuit board is  NOT INTENDED FOR USE IN A DC SYSTEM IF THE DECODER YOU ARE USING DOES NOT SUPPORT IT.

Included with the Tiny board are four axial resistors to be mounted remotely inline and are sized for LEDs. (2.2K)

Onboard resistors on the Mini board are standard 1K smd resistors.

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 and if necessary a third control wire A6 for a LokSound 4 decoder and A10 for a LokSound 5 decoder),

One pair of speaker pads,

Four lighting outputs; A0F, A0R, A1 and A2.

Resistors for use with LED lighting. (separate axial 2.2K)  (Also available with 0 ohm, 750 ohm and custom specified resistors for function outputs. This accommodates some previously installed and "12 volt LEDs".)  It is IMPORTANT to realize that resistors must be used when LEDs are connected to the four lighting outputs of the Tiny!!!  The resistors may be soldered in line when purchased or the included resistors may be soldered inline upon installation.  Remember there are different incandescent lamp voltage requirements and current draw that have to be taken into consideration also.  A single or two separate bulbs may work but multiple bulbs can be problematic.

Resistors included on the Mini are standard and 1K.  Values of the smd resistors appear in a white circle on the package for all smd resistors.

(Until the next batch is produced the board identifying itself as "Tiny" will have axial resistors and only the picture on the package will indicate the correct headlight outputs for direction of locomotive  The correct headlight orientation is shown on the Mini.)
