3.1.2 Base board: Light version
The Light FLEX Base Board, depicted in Figure 3.7, has been designed to be as compact
as possible. The Light Versions uses a simplified power supply circuitry, and thus requires
a more careful power supply than the Full Version. Moreover, there is no integrated
USB programming capability. Examples of target applications for the Light FLEX Base
Board are: distributed, battery-powered applications, like sensor networks; small robotic
applications, i.e., for mobile robot control and sensor acquisition.

power supply connector. Connect the source voltage to the first two pins, named in
figure as V+ and V-.
The power supply of the Light FLEX Base Board varies in the range of 9 - 12V DC.
• JP12: toggle the programming clock line coming from the ICSP programming
• JP13: connects the pull-up resistor to the RX serial line; if unused, the pin is used
• JP15 and JP16: allows to use an external clock oscillator for the dsPIC (R) DSC;
• JP17: allow to toggle the USB shield between GND or PE.

as a regular GPIO pin;
if disabled, the two pins are used as normal GPIO pins;
