Currently for RC servos, there is the:
- Can specify 5.0, 6.0, or 7.4 Vdc power
- Per viewtopic.php?f=5&t=9862#p31367, can only get position when arrived
- Can only supply 5.0 Vdc power
- Per viewtopic.php?f=5&t=9862#p31367, can get position during motion
Currently, I have an application that needs both options. I use the RCC0004_0 and clip the red wire in the servo's wires. I then splice in my own 7.4 Vdc PSU to get the desired supply voltage.
It would be nice if both boards could support both functionalities, or at least RCC0004_0 supports both functionalities.
