Description
This keyestudio capacitive touch module is fully compatible with micro:bit control board.
There are total 6 rings on the module. Note that two G rings, two V rings and two S rings are separately connected. G for ground; V for 3V; S for signal pin(0 1 2).
It mainly uses touch detection IC, which is a digital signal output device.
The touch detection IC is designed to replace the traditional button with a variable area key, featuring low power consumption and wide operating voltage.
When power on the module, it needs a stabilization time of about 0.5 sec. During this time period, do not touch the keypad. At this time, all functions are disabled, and self-calibration is always performed. No touching the key, the recalibration period is about 4.0sec.
Capacitive touch sensors are used in many devices such as laptop trackpads, digital audio players, computer displays, mobile phones, mobile devices, tablets and others.
When using, connect the module to micro:bit control board using Crocodile clip line.
When touch the sensing area, input HIGH level signal to micro:bit signal end, LED on the module will turn on; or else, turn off.
Technical Parameters
- Working voltage: DC 3.0-3.3V
- Output Signal: Digital
- Dimensions: 31mm*27mm*2.5mm
- Weight: 1.7g
- Environmental attributes: ROHS
Connection Diagram
Source Code
Example Result
Connect well the module, then send the source code to the micro:bit main board. Powered on, touch the module’s sensing part, the micro:bit main board will show a heart icon. No touching, the LED matrix will show another icon.
