FAQ

What is the maximum brightness of the flashlight?

The maximum brightness depends on the input voltage and the control signal. It can reach up to 1W of power consumption.

Can I use this flashlight with other microcontroller boards?

Yes, you can use it with other microcontroller boards as long as they support 3.3V - 5V power supply and GPIO control.

Is the flashlight waterproof?

No, the Flashlight Unit is not waterproof. It should be used in dry environments.

How do I adjust the brightness?

Adjust the brightness by varying the PWM signal sent to the CTRL pin from the microcontroller.

What is the lifespan of the LED?

The LED has an estimated lifespan of around 50,000 hours under normal operating conditions.
