Servos on Romeo Board- DFRobot Forum

2012-07-27 19:50:20 Be aware that once you apply more than 5V on servo power terminal, all VCC pins on digitial pin row will have more than 5V. Make sure you don't burn any sensors with that.

5V will be safe for everything. R2D2C3PO

2012-07-27 00:00:03 Not sure. I want to power 10 of these cheap blue 9g Servos. I expect 100-150 mA per Servo at peak.
So 1.5 A total.

2012-07-26 23:51:32 Hi Robert,

I'm not too sure. I will check on that.

How much current do you plan on providing??

Hector

2012-07-26 06:28:00 HI Hector,

what I meant is: what is the max current allowed per pin?

Thanks

2012-07-26 01:55:03 The current per pin will depend on the Servo. The servo will draw enough current for it to operate...

2012-07-26 00:27:30 Thanks a lot Hector.
5V is enough. What about the current? How high can it be per pin using
1. the motor power regulation
2. unregulated power

Thanks

2012-07-26 00:12:36 1. Using Motor Pwr in with the Vin=M_VIN jumper set will distribute 5V to all of the pins. Don't know if this will be enough to power all 10 servos, depends on the servo size.

2. Using "Servo Power in" will provide unregulated voltage to the power pins next to pins D0-D13, but if you plan to use all of these pins for Servo power you would need to free a few of the pins which are normally dedicated to the motor controller, You can do this by simply removing the jumper pins, for the pins you need.

2012-07-26 00:02:24 Hi,

two questions about powering servos on the romeo board.

1. Can I power (10) Servos via the Motor power in? (so I can use the power regulation)
2. Using the Servo power in: which pins get powered with the unregulated power?

Thanks
Robert
