This is a FET driver with a secondary channel, you can run a full power led(s) and a secondary led(s). You can buy complete triple led mcpcb to go with these for complete builds. This driver is rated from 3.0 to 4.5 volts so only power with a single 3.7 volt battery.
3.7 volt driver fet primary output linear secondary output single li-ion input only Designed to work with the mtn mcpcb with spots for three qx-e leds (available here with leds preflowed on mcpcb) but will work with most any dual configuration you can create. 17mm board diameter 1.6mm board thickness
Reversing options(1/2second press) as follows: Turbo--->Strobe--->Batt Check (1-8 with 8 being full) ---> Bike Indicator Strobe
To enter configuration mode, quickly turn off the light 15+ times until it starts to flash. Once it starts to flash, you are in configuration mode. Once in configuration mode, the light will give a solid flash between 1 and 5 times. The number of solid flashes indicates the option number to be changed. To select/change the option turn the light off and back on during the strobing flashes that immediately follow the solid flashes. When you choose option 1 it will start to flash 1-8 times, turn off and back on after the number of the group you want comes up. When setting the temperature control the light will go from programming to turbo, turn the light off when it reaches the temperature you desire.
