The Servo Voltage Regulator allows you to mix 5V servos with high-voltage servos in the same R/C system.  For example, Spektrum receivers are capable of operatinig with a 2-cell li-po battery pack (8.4V).  There are even servos that can handle this higher voltage, but most digital and analog servos can only tolerate up to 6V.  Up until now if you wanted to use a 2-cell li-po battery for your receiver pack, you had to use a large-capacity voltage regulator wired just after the battery to keep the system voltage at 5 or 6V.  Some regulators needed large heat sinks or even miniature fans!  The Servo Voltage Regulator targets the regulated voltage to only the servos that need the lower voltage.  It plugs in-line with your lower voltage servo and steps the 8.4V down to a safe 5.6V, and it even amplifies the servo signal level for long servo wire runs.    

Max Input Voltage - 12V

Output Voltage - 5.6V

Max Current - 1.5A
