The Stamp Controller Interface allows the BASIC Stamp^® microcontroller to connect directly to industrial type digital I/O control boards produced by Opto22, Grayhill, Allen-Bradley, and others that accept 0-5 VDC voltage control levels. These optically isolated modules are ideal for interfacing microcontrollers to the real world, and are more reliable by providing proper isolation. The Stamp Controller Interface accepts the BS1 and all 24-pin BS2 modules, and has a parallel port connection for monitoring status of I/O pins. A clever driver/resistor configuration allows the user to mix and match up to 16 inputs and outputs in any configuration. A 9-12 VDC, 2.1 mm jack is included for external power supply (sold separately).

A BASIC Stamp module or Javelin Stamp module is not included with this programming board.
