Back in March of this year (2020) I posted about the NixTrainz-Decoder-Buddy-v5-21-pin decoder motherboard and its benefits. The only problem with this item is in trying to get it to fit in smaller installations. Its dimensions are 17 mm x 56 mm x 9 mm (0.67” x 2.20” x 0.35”).
To solve this issue NixTrainz has added the Decoder Buddy Mini motherboard to its line of products. See Fig 1.
Fig 1 Decoder Buddy Mini
Dimensions are 17 mm x 35 mm x 9 mm (0.65” x 1.35” x 0.35”). This motherboard has all the connections you would normally expect plus pads for a keep-alive and also a pad for the keep-alive control connection if you install one of those. Resistors for use with LED lighting are included. (separate axial 2.2K) (Also available with 0 ohm, 750 ohm and custom specified resistors for function outputs. This accommodates incandescent lamps or bulbs). It is IMPORTANT to realize that resistors must be used when LEDs are connected to the four lighting outputs of the Mini! 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 voltages and current draw that have to be taken into consideration also.
Suggested retail price for this motherboard is $14.00. The author has seen it for as low as $10.95. It is currently available and in stores.
If you have an idea for a blog post here, let me know. If I can comment on it, I will or I'll see if someone else can and post it.
