We add this new circuit to ensure no problems occur due to potential overdriving when working with transmitters which we haven't tested or users are not sure whether they are high-impedance or not. (So far as we know, most of transmitters are high-impedance. Another reason to apply the new cicuit is to avoid the accidently damage. We did get several reports regarding module failures, which we found out later that most of them happened due to accidently connecting the PPM line to power supply, and burned out the modules.)
