This is a short video demonstrating a 17 Channel Configurable Multifunction $5 DCC Decoder Supporting Servos that you can build for about $5. This version supports configuring each of the 17 function pins for On/Off (LED/TTL) Control, or Configurable Blinking Control, or Configurable Servo Control, or Configurable Pairs Blinking Control. Yes, that does mean it can support 17 servos, each with rate, start point, and end point setting via DCC CV’s, per pin, as well as new LED configurable functions. You can learn how to put it together here:
