MPR121 Breakout Capacitive Touch Sensor Module

The MPR121QR2 Breakout Board is a convenient interface for Freescale's MPR121QR2 capacitive touch sensor controller. It communicates over I2C and can manage up to twelve individual electrodes. Here are the main features and specifications:

Features:

Capacitive touch sensor controller

I2C interface for communication

Control for up to twelve individual electrodes

Simulated thirteenth electrode

Eight LED driving pins (can be configured as electrodes or used for driving LEDs)

Address jumper for setting I2C address (default: 0x5A)

Jumpers for SDA, SCL, and interrupt pin with 10K pull-up resistors

Operating voltage: 2.5V to 3.6VDC

VREG pin at 2.5V with a 0.1uF capacitor to ground

Specifications:

Material: Alloy + Plastic

Application: Capacitive Touch Sensor Controller

Working Voltage: 2.5-3.6V

Dimensions: 6 cm x 3 cm x 2 cm

Note:

The board doesn't have its own voltage regulation, so the supplied voltage should be between 2.5 to 3.6VDC. The VREG pin is set at 2.5V.

This breakout board provides an easy and efficient way to utilize the capabilities of the MPR121QR2 capacitive touch sensor controller, making it suitable for various applications involving touch sensing and control.
