6-channel Capacitive Touch Sensor Module by EVO - Complete Guide (Images, Details, Specifications, Connection Diagram, Codes)

Tired of clunky buttons?

The 6-Channel Capacitive Touch Sensor Module will add a sleek and modern touch interface to your electronics projects. This module replaces those clunky mechanical buttons, with a sleek touch interface.

This module acts like 6 individual touch switches. The primary application focuses on replacing the mechanical switch or button. These keys can also be used as inputs for micro-controllers. It can independently handle the 6 touch pads using 6 direct output pins.

Specifications:

• Onboard 6-key capacitive touch sensor IC: This is the heart of the module, responsible for detecting your touches.
• Effortless Integration: Simply connect it to your microcontroller using the six direct output pins.
• Power & signal indicator LEDs: Onboard LEDs provide clear power and signal status indications.
• Configuration mode: This allows you to fine-tune the sensitivity of the touch pads if needed, especially when using overlays.
• Low Power Consumption: Operates efficiently at a convenient 3.3 volts, ideal for battery-powered projects.
• Compact Design: The module's small size (45mm x 50mm) makes it easy to integrate into projects with limited space.

There are 2 modes of operation :

• Switch Mode
• Configuration Mode

1 x 6-Channel Capacitive Touch Sensor Module

1 x Microcontroller Unit (Arduino)

6 x LEDs

6 x Resistor

Jumper wires

Breadboard

1 x USB to UART converter (configuration mode)

It can be used as individual switches. The output of the touchpad is ACTIVE LOW. ie, in default condition output is HIGH and whenever a key is pressed the output will be LOW. So, it can be directly connected to LEDs negative terminal and LEDs will Turn ON when key is pressed.

1. Make the connections according to the given circuit diagram.
2. Start using it as ordinary buttons.

It can be used as an input device for a microcontroller unit. The output of the touchpad can be connected to GPIO pins of any microcontroller.

1. Make the connections according to the given circuit diagram.
2. Read the GPIO pins to get the touchpad signal.
3. Start using it as input device for the project.

This touchpad can be used with glass or wooden overlay for better appearance. You need to change the touch sensitivity to use overlay.

You can connect to any UART devices for configuration.

Connect the jumper between CONFIG pin and GND pin to enter configuration mode.

Key 5 will act as RX , Key 6 will act as TX.

Connect touchpad --> USB - UART converter

Key 5(RX) --> TX

Key 6 (TX) --> RX

GND --> GND

+3.3v --> Vcc

Connect USB to Computer

Open Terminal and locate the serial port where touchpad is connected.

Use the following AT commands to increase or decrease the touch sensitivity.
