The only thing is the servos are smaller than standard servos. I am sure there is a way to make it work. Obviously there is some time to work it all out.

you should be able to still use those servos but only send not receive with the v3... should still work

Thank you DJ. I may have more questions once I get everything but now I feel better. Thank you

So I think this has been covered but I can't seem to find the answer, Will the V4 support serial Tx and Rx? If so, that would be done on two ports, correct?

As far as modifying the plug, if the servos wires are Gnd,Vcc,Rx,Tx then you could just plug it in. It shouldn't matter if the Servos Tx is connected because the V3 can't read it anyway.

@Antron, that is what I understand to be correct, V4 has Tx and Rx capabilities, each would require a separate port of the EZ-B.

Also, yes, if the pin out is Ground, VCC, Rx, Tx then you could plug it in with the Tx no connected to anything and it should work without any plug modifications. Failing that, you could make up a small conversion board with 0.1" headers to re-route the pins in to the correct order or use jumper wires to do so.
