The FLEX Light, depicted in the picture below, has been designed to be as compact as possible. The Light Version uses a simplified power supply circuitry and there is no integrated USB programming capability. Target applications for the FLEX Light could be: distributed, battery-powered applications, like sensor networks; small robotic applications, i.e., for mobile robot control and sensor acquisition, etc.

The power supply of the FLEX Light varies in the range of 9 - 12V.
