Is Expansion Board Servo Voltage Suppose to Be 9v

Hello again,
    I was surprised to find that my expansion board servo ports were putting
9 volts. Is this the way the board was designed or is this in error. Most
servos I have come across work in the upper 4 to 6 volt range. The servo I
have runs uncomfortably hot when using the expansion board (and the standard
9.6v battery, in other words in not using a secondary power supply).

Do you have the dropping 2n540x diodes in place? they should drop the 9.6v batt to the 5-6v servo voltage. Fred (...) (23 years ago, 15-Aug-01, to lugnet.robotics.handyboard)
