This is a quick start guide for LTC3210
Demonstration circuit 914 is a multi-display LED controller featuring the LTC3210, a low noise charge pump designed to drive four MAIN LEDs and one high current CAM LED. The board uses a PIC controller to interface between the DC590 board and the LTC3210 over a 2-wire I2C serial interface, and the guide states that the LTC3210 requires only four small ceramic capacitors plus two resistors to form a complete LED power supply and current controller.
The quick start procedure covers connecting DC914 to the DC590 USB Serial Controller with the supplied 14-conductor ribbon cable, applying a 2.9 4.5V source to Vin and GND, and running the QuikEval program. The guide also describes the QuikEval controls for MAIN and CAM brightness, flash settings, pulse timing, gradation, and resetting the PIC.

It is a multi-display LED controller featuring the LTC3210, which drives four MAIN LEDs and one high current CAM LED.
The guide says to attach a 2.9 4.5V power source to the Vin and GND turrets of the DC914 demo board.
Connect it to the DC590 USB Serial Controller using the supplied 14-conductor ribbon cable, then run the QuikEval program.
When selected and released, it flashes the CAM LED at the ENCF intensity for the time selected in the FLASH TIME drop-down window.
