We don't sell many of these, because very few people need them. But we added a new board with Barrier Terminal Strips. The original screw terminals work fine for indoor applications with bare wires, but when outdoors, the wiring tends to be much larger in both gauge and diameter of the insulation. The Barrier Terminal Strips, used in conjunction with spade lugs make the connections a lot easier.
Again, PWM (Pulse Width Modulation ) outputs, such as used on the RailBoss 4 and TrackSide R/C, do no harm to your motors, but in some cases they may make lights flicker. This filter will eliminate that.
