Capacitive Touch LED Dimmer PWM Control Switch Module for Indoor LED DIY Automotive Lights Dimming Refit

Jumper Settings:

1. T1 = 1, T2 = 1 corresponding: LED touch step-less dimming without brightness memory
2. T1 = 0, T2 = 1 corresponding: LED touch step-less dimming function without brightness Memory fading
3. T1 = 1, T2 = 0 corresponding: LED touch step-less dimming function with brightness Memory fading
4. T1 = 0, T2 = 0 corresponding: led three touch dimming function

Touch Functions:

A) when the touch is clicked (the touch duration is less than 550ms), the light on/off control can be realized. Once click touch, the light is on; once click touch, the light is off. This cycle. When the light is on or off, there is no brightness buffer. And the initial brightness of the light is fixed at 50% of the full brightness.
B) Press and hold the touch for more than 550ms to gradually increase the brightness of the light. When released, it stops at the brightness corresponding to the release time. If the press for a long time is more than 3 seconds, the brightness of the light will not change after reaching the maximum brightness.
C) Click the touch to turn on and off the light, the light smoothly reduces from the current brightness until it is turned off It can achieve the visual buffering effect of slowly changing brightness and protect the eyes and vision.
D) Under continuous power supply, the brightness will be memorized each time turn off the light, and the next time you click the touch to turn on the light, the brightness will be used as the initial brightness. In case of power failure, the first time after power on, click touch to turn on the light, and the initial brightness is fixed at 50% of the full brightness.
E) LED three touch dimming function: Click the touch, the light brightness is in the order of low brightness → medium brightness → high brightness → off

Debugging tips:

If it is triggered by mistake or not during debugging, it

Specification:

• Installation: without direct contact with copper foil, dimming can be carried out by more than 3mm acrylic glass or plastic.
• Voltage range:2.4-5V; Maximum output current:500MA; Hole distance:16MM; Aperture:2.5MM
• Function: single line touch, using the principle of capacitive touch, sensitive touch. By default, it has switch function, dimming function and stepless dimming function of LED touch with brightness memory. Turn on the light slowly, turn off the light slowly dark, effectively avoid eye irritation.
• Wiring mode: in PCB board (VCC, GND) is power input, (LED +, led -) is led lamp positive and negative (fingerprint) is touch area, and it can also be wired out (note that the wiring should not be too long, after the outgoing line, it is recommended to use a small copper sheet as the sensing area), and the copper sheet area is recommended to be 2x3cm left and right. The copper foil module on the board pastes one side of the copper foil on the shell side.
• Dimming mode: stepless PWM dimming; Initial powered on, the lamp is off.
