Current Draw Requirements

Nearly all servos are designed to run on about 5 or 6v. Keep in mind that a lot of servos

moving at the same time (particularly large powerful ones) will need a lot of current. Even

micro servos will draw several hundred mA when moving. Some High-torque servos

will draw more than 1A each under load.

Good power choices are:

5v 2A switching power supply (http://adafru.it/276) (up to perhaps 4 servos)

5v 4A switching power supplies (http://adafru.it/e50) (up to perhaps 8 servos)

5v 10A switching power supply (http://adafru.it/658) (up to perhaps 16 servos)

4xAA Battery Holder (http://adafru.it/830) - 6v with Alkaline cells. 4.8v with NiMH

rechargeable cells, portable!

4.8 or 6v Rechargeable RC battery packs from a hobby store.

SERVOS CAN USE A LOT OF POWER! It is not a good idea to use the Raspberry Pi's 5v

pin to power your servos! Electrical noise and 'brownouts' from excess current draw

could cause your Pi to act erratically, reset and/or overheat. Seriously, keep the Pi
