180-Degree Servo Signal Expander for Multi-Servo Control

A receiver only has so many channels, and a build that needs more simultaneous servo movement than it has channels available usually ends up either buying a receiver with more channels or finding another way to split an existing one. This expander takes that second route, letting one channel drive multiple 180-degree servos together - a practical workaround for a retrofit or an add-on function that doesn't justify a full receiver upgrade just for one more moving part.
