 | | Is Expansion Board Servo Voltage Suppose to Be 9v —Andrew Loy
|
| | | 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 (...) (23 years ago, 15-Aug-01, to lugnet.robotics.handyboard)

| | | | 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)

| | | | Yes, Fred, the diodes are in place. I Assume that is where I should start to test for opens, shorts and, bad diodes. Thanks for the help. Andy "Fred G.

| | | | Make sure you measure the voltage under load. Without a load the diodes won't look like they're dropping anything. Fred (...) (23 years ago, 15-Aug-01, to lugnet.robotics.handyboard)
