Parallax's PWR-I/O-DB is a daughterboard that plugs into the BASIC Stamp 2pe Motherboard. It provides both power and a handy interface to potentiometers and servos, along with Parallax's various three-pin devices, including:
The addition of an onboard voltage regulator and filtering ensures that servo noise and other intermittent loads will not disturb operation of the motherboard.
