Can I use a Max232 RS-232 Driver to drive a RC Servo

CanYouC3D

Hi All

I would like to use a Max232 Driver to drive a RC Servo from· 100 to 300 ft. away.
PW sig. would come from a BS1 in to MAX232·TX with some control lines returning.

I know I can use·two (one·for TX and one for RX)·BS1 but I would like to use just one.

Thanks

You might want to use an RS-485 device instead as they're designed for long distance (RS-232 really isn't). The thing you want, of course, is accrurate reproduction of your pulse on the receiving end so your servo gets positioned properly. This shouldn't be a problem because a 1.0 ms pulse equates to about 100 baud (if 1.0 is use as the bit width).
