I would have liked to have done this. It would have made my job much easier. But, the reality is that every transmitter uses a different set of controls for programming inputs, such as rotary wheels vs. scroll wheels, buttons vs. switches, etc. There really is no way to make a "universal" type board because you are going to also need a board to hold an encoder, push buttons, etc. You might as well make that same board hold everything.
