Decoder Buddy from Nix Trainz is a 21-pin-friendly replacement motherboard for the standard factory-supplied DCC 8-pin loco motherboard in many locomotives. It allows you to take full advantage of all the functions and features of the latest decoders. This board allows easy 21-pin decoder installs from vendors such as Digitrax, ESU, SoundTraxx, TCS and NCE!
Depending on your DCC decoder, up to 12 lighting functions are available. The Decoder Buddy board features amply sized soldering pads for your LED leads. LED installation is also possible with built-in resistors already on the Decoder Buddy board.
The benefits of the three Decoder Buddy models include:
No more inaccessible JST connections
Decoder Buddy fits most HO and larger locomotives. The standard board measures 2.20 x 0.67 x 0.35" 56 x 17 x 9mm and a Decoder Buddy Mini is available for tighter installations.
