Common anode connection:
For example, control of a 12V strip: VCC of a 12V power connector module.GND of the negative module.The controlled lamp has the VCC of the positive module. OUT of the negative module. After being powered on, the touch panel can be used to control the light strip, and the brightness of the light can be adjusted by touch.
For example, control of 12V motor speed regulation: VCC of the positive electrode module of a 12V power supply. GND of the negative module. VCC of the positive pole of the controlled motor. OUT of the negative module. After power-on, the motor can be controlled by a finger touch module, and motor speed control can be achieved by touch.
Control interface:a total of 3 pins (VCC, GND, OUT), VCC as the power supply, GND as the ground, OUT as the digital signal output pin;
LED indicator:electric green (blue) light, touch sensing output red light.
Touch area:The inner area of the fingerprint icon is triggered by a finger touch.
Positioning hole:2 M2 screw positioning holes, 2mm aperture, easy to install and position the module, to achieve module combination.
Application:12V light bar (LED) brightness adjustment touch. 5-20V DC motor speed control.
Memory mode:the last brightness of the module set to boot the default brightness, the system power-down memory default value will be lost
Gradually brightening:light brightness gradually open to set the brightness, turn off the lights when the brightness gradually closed
Sudden bright light:lights when the brightness directly to set the brightness, turn off the lights when the lights directly off
Long press touch:to achieve stepless dimming, a long press touch, the brightness of the light gradually increased, the brightness of the light when the release time to release the brightness of the release, once again press the touch, the brightness gradually reduced.
When the brightness of the light when the release of the brightness of the release time, for motor speed, output voltage regulation and other occasions
Refit for automobile motorcycle this module, the majority of customers, LED lights and lamp, mirror touch, and all kinds of need to directly load equipment and so on.
Touch module can be set point or latch, the sensitivity adjustable (highest welding capacitor. Zero. The default delivery), can also lead out of touch.
Lamp: on the blue light output, touch the red light output;The output is equal to the input.
Input/output DC: 6 v - 20 v (note: support regulated power supply, temporary tired constant current power supply)
Drive current: 3 a standby consumption: 6 ma circuit board size: 24 MM * 32 MM * 1.6 MM
At present, a lot of cooperation customers used to develop a touch switch, LEDThe lampA modified,Car modification,The chamber of secrets escape game, each big machines products equipment, etc.
Can be widely used in lighting control, toys, household appliances, kitchen, bathroom mirror, etc.
MPR121 Breakout V12 Capacitive Touch Sensor Controller Module I2C keyboard |
Description: This is a breakout board for Freescale&x27;s MPR121QR2. The MPR121 is a capacitive touch sensor controller driven by an I2C interface. The chip can control up to twelve individual electrodes, as well as a simulated thirteenth electrode. The MPR121 also features eight LED driving pins. When these pins are not configured as electrodes, they may be used to drive LEDs.
There a four jumpers on the bottom of the board, all of which are set (closed) by default. An address jumper ties the ADD pin to ground, meaning the default I2C address of the chip will be 0x5A. If you need to change the address of the chip (by shorting ADD to a different pin), make sure you open the jumper first. Jumpers also cont SDA, SCL and the interrupt pin to 10k pull-up resistors. If you don&x27;t require the pull-up resistors you can open the jumpers by cutting the trace conting them.
There is no regulation on the board, so the voltage supplied should be between 2.5 and 3.6VDC. The VREG pin is conted through a 0.1uF capacitor to ground, which means, unless you modify the board, you can&x27;t operate the MPR121 in low-supply voltage mode (1.71-2.75VDC).
Size:3cm x 2cm .

Feature:
The brightness of the lamp can be adjusted by request, which is very operational.
It can be protected in the middle, such as glass, acrylic, plastic, ceramics, etc. It is very safe to touch.
Simple application circuit, few peripheral devices, easy processing, low cost.
Anti-power and telephone interference, EFT can achieve the above +/- 2KV; touch response sensitivity and reliability will not be affected by proximity or multi-angle mobile phones.
Installation: no need to directly contact the copper foil, dimming can be processed in acrylic glass (3mm or more) or plastic.
Application:
It can control LED modules, lights, etc.
He can be used for indoor LED lighting, DIY car light dimming modification.
Function:
Single touch, use capacitive touch.
The principle of the default function is switch, dimming, brightness recall LED touch dimming.
It will turn on when it is slowly lit, and it will become darker when it is turned off, effectively avoiding eye irritation.
Dimming mode: Non-polar PWM dimming.
Wiring method:
PCB board (VCC, GND) power input
(LED +, LED-) is connected with the LED street light of the positive and negative level (fingerprint) touch area, and can also be led by wire (the wiring should not be too long), the copper skin area should be 2x3cm.With the copper foil copper plate module side To the side of the shell.
Using method:
a.Click touch (touch duration is less than 550ms), you can control lamp.Click once, the light is on;
Click again, the initial brightness of the light off. The light is fixed at 90%, then the entire brightness.
b.Press touch for a long time (touch duration exceeds 550ms), can achieve stepless dimming lights.
Pressing for a long time, when the light is released after the corresponding brightness release time, the brightness of the light gradually increases the light intensity. If the time is longer than three seconds, the brightness of the light will not change until the maximum brightness is reached; once again, the brightness of the light gradually decreases. To stop, when you release the light level at the corresponding brightness release time, if the time is longer than three seconds, the light level will not change after reaching the minimum brightness.
