J5 - LEDs - is the jumper used to connect the on-board flash LEDs to the LED output of the driver.
STROBE - This pin provides an external method for initiating a flash or torch event. The STROBE pin is
connected to ground via a 300 K

resistor internal to the LM3565. To externally drive this pin, either
connect a control signal directly to the STROBE pin of the connector or place a jumper between connector
pins STROBE and PWM0. Pin PWM0 can be configured as ON, OFF, time-adjustable voltage pulse or
continuous voltage pulses of adjustable frequency and duty cycle via the General User Interface software
provided.
