The EFX Controller Board is a controller designed to meet the needs of anyone involved in small-scale industrial control as well as prop builders and effects technicians. The EFX Controller Board combines a Parallax BASIC Stamp 2 microcontroller core with two high-current sink drivers (ULN2803), allowing the user to connect devices like relays, solenoids, and lamps directly to the controller. Dual connections are provided for all I/O pins (3-pin header for TTL input/output connections; terminal block for high-current outputs).

This product is also known as a Prop-2 Controller Board, but it is not part of the Propeller product line.
