I/O Controller 8-8-8, Hub

Product Description
The 8/8/8 Input/Output, Hub Controller provides
* 8 Analog Inputs
* 8 Digital Inputs w/hardware noise filtering
* 8 Digital Outputs
* On-board powered 6-port full-speed (12Mbit/s) USB hub
Analog inputs are used to measure continuous quantities, such as temperature, humidity, position, pressure, etc.
These digital inputs have a hardware filter to eliminate false triggering from electrical noise. They can be used to convey the state of these devices: push buttons, limit switches, relays, and logic levels.
Digital outputs are used to drive LEDs, solid state relays, transistors and anything that will accept a CMOS signal.
Connecting additional USB devices is as easy as plugging them into the on-board 6-port hub. Each USB port on the hub has a maximum current supply of 500mA.
Expand your robot's standard I/O configuration from 24 to 48 ports by adding a second I/O, Hub board.
Expand your robot's standard USB configuration from 6 to 12 USB ports by adding a second I/O, Hub board.
