This is the 3.04A qlite driver, loaded with momentary firmware (for a separate electronic switch; not a normal rear clicky switch).  The electronic switch is soldered to ground and Star 4 (which is also MCU pin 2).  

If your light has a switch in the back it is likely that you DO NOT have a momentary switch!  If your switch disconnects the power to the driver then it is not a momentary switch and you should use the normal qlite driver instead.

FIRMWARE OPTIONS

1. STAR Firmware

The user interface is simple and intuitive: a short press moves you forward one mode, a long press moves you back one mode.  From off, you can instantly switch to either the lowest or highest mode, then back to off with another single press or hold!  Low-voltage stepdown and an optional turbo-timer make this a fully featured driver.  No blinky/strobe modes.  

Mode Selections: (non-user selectible, hard programmed)

1. 15% - 100%
2. 2% - 25% - 100%
3. Moonlight - 2% - 25% - 100%
