It sure seems like Futaba and JR have caused quite a mess with the new lower voltages, but it is the way of the future. The chipset in our new "Autosequencer" works down to 2V and uses a separate power supply lead for the MCU (chipset) power which automatically boosts the output signal to the servos or valves without the need for an opamp. We plan on offering 2 voltage supply system ranges for our new gear/door sequencer. One for the low voltage systems 3.3V or less and one for the older higher voltage systems using 5V logic chipsets to try to combat all the compatability issues now surfacing. As the industry changes to the lower power chipsets, we, the aftermarket suppliers are doing our best to keep up with all the changes. New chipsets are becomming available with an operating voltage down to 1.8V and I'm sure the voltages will be driven even lower as the market demands. It costs a lot to keep up these days. Microchip programmers have to be upgraded when changing to the lower voltages since the older programmers are based on the higher voltage chips as well, so it is has not been much fun for the aftermarket electronics manufacturers either. It would be nice if the radio equipment manufacturers would start keeping everyone in the loop when these changes are going to be, or have been made, without leaving all of us to figure out what is going wrong with our equipment.[]
