Module Capacitive Touch Dimmer Constant Voltage LED Stepless Dimming PWM Control Board Dimming Switch Module

 Features:
The touch dimming module can realize the touch switch control and brightness adjustment of the LED light. Has the following features and advantages:

1. The brightness of the light can be adjusted as needed, the selection range is wide, and the operation is simple and convenient.
2. The touch function can be realized under the condition of isolation protection of medium (such as glass, acrylic, plastic, ceramics, etc.), and the safety is high.
3. Wide application voltage range, can be arbitrarily selected between 2.4~4.5V.
4. The application circuit is simple, the peripheral components are few, the processing is convenient, and the cost is low.
5. Anti-power interference and mobile phone interference characteristics are good. EFT can reach ±2KV or more; in the case of short-distance, multi-angle mobile phone interference,
Touch response sensitivity and reliability are not affected.

6. Installation: no direct contact with copper foil, dimming through acrylic glass or plastic of 3mm or more.

7. Use: It can control LED modules, lamp strips and other products. Suitable for indoor table lamps, LED lighting dimming, DIY lamp dimming and conversion of the best accessories.

8. Function: Single-line touch, using the principle of capacitive touch, the sensitive touch tentacle can be. The default is a stepless dimming function with LED function, dimming function, and LED touch with brightness memory gradually faded. It lights up slowly when the light is turned on, and slowly darkens when the light is turned off, effectively avoiding eye irritation.

9. Dimming mode: stepless PWM dimming

10. Wiring method: PCB board (VCC, GND) is the power input, (LED+, LED-) is connected to the LED lamp positive and negative (fingerprint) for the touch area, but also for wiring (note that the wiring is not too long, the outlet After the introduction, use a small piece of copper to make the sensing area), the copper area is recommended to be about 2x3cm. The copper foil module on the board attaches one side of the copper foil to the side of the outer casing.

11. How to use

a) When the touch is touched (touch duration is less than 550ms), the lighting can be controlled. One click touch, the light is on; once click on the touch, the light is off. The initial brightness of the light is fixed at 90% of full brightness.

b) When the touch is long pressed (touch duration is longer than 550ms), the stepless brightness adjustment of the light can be realized. When the touch is pressed for a long time, the brightness of the light gradually increases. When the light is released, the brightness of the light stops at the brightness corresponding to the release time. If the long time exceeds 3 seconds, the brightness of the light does not change after reaching the maximum brightness; once again, the touch is long pressed. The brightness of the light gradually decreases. When the light is released, the brightness of the light stops at the brightness corresponding to the release time. If the long press time exceeds 3 seconds, the brightness of the light does not change after reaching the minimum brightness.
Turn. This cycle.

12. Debugging tips

If a false trigger occurs during debugging, or does not trigger, it may be caused by the following reasons:

a) The touch line is too thick

b) The touch line is too long

c) copper is not big enough

d) disturbed near the power supply end of the switch

e) Touch parameter C1 is unreasonable

Technical features:

TI touch input corresponds to LED light control output. There are four functions to choose from, before the power is turned on by the T1 and T2 pins.

State to decide. details as follows:
1.T1=1, T2=1 Correspondence: LED touch stepless dimming function without brightness memory
