Parallax Propeller Control Board


The Propeller Control Board is a complete solution for controlling robotics platforms. This is the same control board that ships with the Parallax QuadRover robot. The Propeller Control Board is capable of interfacing directly with the Parallax GPS Module, our Hitachi HM55B Compass Module and our Hitachi H48C 3-Axis Accelerometer.  This provides options for tracking position, heading and acceleration for robotic applications.

12 of the Propeller I/O pins are brought out for customer interfacing and control applications, 8 are dedicated to servo control and 8 are dedicated to N-Channel MOSFET outputs, providing high-current drivers for solenoids or other high-current devices. There is also a magento-pickup compatible tachometer input which can be used for measuring the RPM of gasoline engines.

The power switch allows you to turn all power off, only the Propeller on or the Propeller and servos on. There is also a reset button for the Propeller chip. A socketed 5MHz crystal is included
