Servo Control Voltage

I don't have a scope to verify this but would I be correct in assuming that the servo control voltage going to the servo is 3.3 volts on any particular digital port that a servo is connected to on an EZ Controller? The power to the servo would be the battery voltage that the EZ Controller is powered up from which is typically 7.2 Volts? Thanks...

Two 7.4 Volt 360 Servo Step Up To 48 Volt 1000 Watt Motors

Looking for recommendations on commercial fabrication of h-bridge for above. Burned up one electrical engineer (not literally) who tried to hook up ezb4 with 48v motor. Looking for someone who is honorable and wants a good day's work for a good days pay. Telemetry 100% complete, body 90% complete, mechanics 90% complete. Perferr performance...

Ez-B And Arduino Shield

After upgrading and swapping to the newer EZ-B board, it would be a shame not to use it with another robot. any consideration to building an Arduino Shield to accommodate the EZ-B? It would be overkill to add an EZ-B to an Arduino, but the potential would open up a wider market and audience. Perhaps the addition of an Arduino Library as well?...
