Light Cotroller PCB

Finished the prototype of the light controller last night.  Here is the PCB model.

The functionality that finally got implemented is as follows:
1. The six LP5569 LED engines were spread across the three connectors on the left, each one has two.  There are 3 LED connections per engine for a total of 6 LEDs and 4 power connections.  The connector is a standard 10 pin header and any PC 10 pin ribbon cable can be used to connect the LEDs.
2.  The connector on the bottom has the two PIC PWM engines and the two ON/OFF LEDs plus two power connections.  This connector is a the same connector used to power the Brick BuddyTM . I will have more on this later this weekend.
3.  The input control was changed to three ON/OFF type contacts and one analog input.  This way you could set the brightness or the blinking rate or who knows what I will dream up.  Again uses the same 6 pin connector as #2 above, with these four inputs and power/ground.
4.  Included a RN4020 BLE module, though I will probably not implement the firmware at this time.  This is more of a set it and forget type functionality, at least now.

The PCB fabs should be back next week, so maybe by next weekend something will be up and running.
