TTP223 Capacitive Touch Switch Button Self-Lock Module Sensor for Arduino, RPi

Description

TTP223 Capacitive Touch Switch Button Self-Lock Module Sensor for Arduino, RPi
These little touch sensors are really easy to use. Just apply power, and connect the output to your Arduino, Raspberry Pi, or other microcontroller. When it starts up it calibrates itself to the environment, so you don't have to be especially careful about stray capacitance around it. It will sense through a thin plastic panel on a project box, so you don't have to put holes in your box to add a switch.
There is lots of info on the internet, and on youtube, on hooking these up and how to control its behavior with the A and B jumpers.
Pins: GND, I/O, VCC
Power Supply: 2.5V~5.5V
Dimensions: 15*11mm(approx)
Color: Red(as pictures show)
With the A and B jumpers you can control:
whether the output is high when pressed, or low when pressed
locking or non-locking operation
These are excess items I bought for a project and didn't need. They were bought new and have not been out of their bags.
Shipping on any quantity you purchase is a flat charge. I usually ship same or next day, depending on when payment arrives.
