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.

The addition of an onboard voltage regulator and filtering ensures that servo noise and other intermittent loads will not disturb operation of the motherboard.

Key Features:

  • Motherboard connector: compatible with the MoBoStamp-pe and all future Parallax motherboards   
  • Multiple power sources: +5V and Vin can be provided from either the motherboard or the onboard power jack and regulator   
  • Interface headers: six three-pin headers (ground, +5V, signal) to interface with external devices   
  • Onboard power filtering: 1000 uF filter cap for maximum suppression of noise and load transients

Application Ideas:

  • Robotic Controls
  • Custom Sensors
  • Data Acquisition Circuitry
  • Industrial Control I/O
  • Pushbuttons and LEDs  


  • Wall transformer (or battery) input: 2.1mm coaxial power jack, 6-9 VDC (compatible with Parallax #750-00009)
  • Power requirements:4 to 5 VDC from motherboard or 6 to 9 VDC from external supply
  • Dimensions:1.35 x 1.35 x 0.68 in (34.29 x 34.29 x 17.39 mm)
  • Operating temp range: -32 to +158 °F (-0 to +70 °C)
