Digital I/O Connector
This Digital I/O connector can be used in various industrial applications like
programmable logic devices and embedded, custom applications that make
heavy use of GPIO for reading from various environmental sensors (IR, video,
temperature, 3-axis orientation, and acceleration), and for writing output to DC
motors (via PWM), audio, LCD displays, or LEDs for status. Its isolated Digital
I/O pins provide electrical protection to the system, preventing high current
devices and high voltages from damaging the system.
