Convoy MK LED Flashlight Drive Board SST40 Circuit Plate for S21A / M21A - Red 20MM

Main Features:
This 12 groups sst40 driver is compatible with lighted switch.
Its biggest advantage is that no frequency can be seen in any mode, and there is temperature management.
It can control the flashlight temperature not to exceed 55 degrees Celsius.
If the flashlight temperature is below 55 degrees Celsius, it will output full current. If it is above 55 degrees Celsius, it will constantly adjust the current so that the flashlight will not overheat.
Enter into mode group selection
After clicking, the light should come on in a special group-select mode. In this mode, it slowly blinks out numbers from 1 to N, where N is the number of mode groups, then repeats. Turn the light off after N blinks to select mode
group N. BTW, do not leave the light in config mode for long periods of time, because it will wear out the drivers memory faster.
