So a couple of addtional questions are needed to answer that.

1. Are you going to use all 4 transducers independantly?  
2. Are you going to use all 4 simultaneously?   There are issues with this.
3. Do you want to send a pulse out of 1 and receive on all 4 looking for multipath issues?
4. Do you have a controller / strategy in mind yet?   If you are trying to use a specific controller board, that would be useful to know.

Paul

Hello everyone,
Is there a way to drive 4 transducers with one controller board?   Does anyone know how dpa is doing it in jBot?

Thanks,
Duane
