💎【TTP223 Digital Capacitive Touch Sensor】
⚡【Supply Voltage】:2.5~5.5V DC
🥇Support 6 seconds self-lock
🥈Support self-calibration
🥉Support module is mounted in the surfaces of non-metallic materials such as plastic, glass, acrylic, you can make the keys hidden in the walls and desks.

Welding Way:
Trigger setting mode:(1- Greater than Short;0- Greater than No Short)
AB=00:No-lock High TTL level ouput;
AB=01:Self-lock High TTL level ouput;
AB=10:No-lock Low TTL level ouput;
AB=11:Self-lock Low TTL level ouput;
Note:
Welding towards the middle spot

Pin 1: output high level is power supply voltage, low level is 0V. Under condition of VDD=3V, output current is 6mA and input current is 10mA. Able to directly drive an LED (current limiting resistor 1K need). it is recommended to set the IO port of MCU to high-impedance input mode;
Pin 4: Determines initial output voltage of pin 1. Pin 4 is grounded, and the initial output voltage of pin 1 is 0V. Pin 4 is connected to power supply, and initial voltage of pin 1 is equal to power supply voltage. After changing the state of pin 4, the power must be turned off and then on to take effect;
Pin 6: Determines the working mode of the chip. Pin 6 is grounded, and the chip is in synchronous output mode. Pin 6 is connected to the power supply, and the chip is in level conversion mode. After changing the state of pin 6, the power must be turned off and then on to take effect.
The panel pattern can be designed at will, size and shape of button can be freely selected, and characters, trademarks, perspective windows can be arbitrarily matched.
