Working Mode(You can move the resistor to change the working mode):
When power on, the LED is OFF; First trigger button,the LED is ON 100%; Second trigger button,the LED is ON 25%; Third trigger button,the LED is 8HZ flashes; Fourth trigger button,the LED is OFF. Press and hold the button for 3 seconds, SOS function
Pin Description:

IN+: Power Supply-
KEY: Switch(button) port
L+ : LED Output +
L1-: LED Output 1- (Direct output)
L2-: LED Output 2- (Onboard 1.6¥Ø current limiting resistor)
L3-: LED Output 3- (Onboard 0.8¥Ø current limiting resistor)
Note: This product has no current limiting function, the maximum load current cannot exceed 1.5A, otherwise the chip will be burned.
LED Drive Current Setting
The LED driving current can be realized by adjusting the value of the current limiting resistor R
The value of resistor R can be adjusted according to the required current:
ILED=(VIN-VF-0.3)/R
(VIN is supply voltage, VF is LED forward voltage)
Example 1 (L2- Port): Power supply voltage 3.8V, VF=3V, R=1.6¥Ø,
Then ILED=(3.8-3-0.3)/1.6= 0.3125MA
Example 2 (L3- Port):Power supply voltage 3.8V, VF=3V, R=0.8¥Ø,
Then ILED=(3.8-3-0.3)/0.8= 0.625MA
