Adding a Capacitor to the thru-hole capacitor slot

We have a spot on the PCB for soldering in an electrolytic capacitor. Based on your usage, you may or may not need a

capacitor. If you are driving a lot of servos from a power supply that dips a lot when the servos move, n * 100uF where

n is the number of servos is a good place to start - eg 470uF or more for 5 servos. Since its so dependent on servo

current draw, the torque on each motor, and what power supply, there is no "one magic capacitor value" we can

suggest which is why we don't include a capacitor in the kit.

Connecting a Servo

Most servos come with a standard 3-pin female connector that will plug directly into the headers on the Servo Driver.

Be sure to align the plug with the ground wire (usually black or brown) with the bottom row and the signal wire (usually

yellow or white) on the top.

SERVOS CAN USE A LOT OF POWER! It is not a good idea to use the Arduino 5v pin to power your servos.

Electrical noise and 'brownouts' from excess current draw can cause your Arduino to act erratically, reset

and/or overheat.
