Adafruit CAP1188 - 8-Key Capacitive Touch Sensor Breakout - I2C or SPI

Add a wave of interactivity to your next microcontroller project with the 8-channel capacitive touch sensor breakout board, featuring the advanced CAP1188. This innovative chip manages up to 8 individual touch pads, making tactile controls more responsive and reliable.

Each triggered touch sensor lights up one of the 8 onboard LEDs, simplifying the debugging process. With seamless communication through both I2C and SPI, it easily integrates into any microcontroller setup. The I2C interface even allows selecting from 5 different addresses, enabling up to 40 touch pads on a single 2-wire bus.

The CAP1188 eliminates the complexities of capacitive sensing by handling all necessary filtering, and offers adjustable sensitivity to match your specific needs. The board is fully assembled, ready to slip into a breadboard with the included 0.1" header strip. To create touch contacts, use copper foil, and link it via soldered wires to the breakout.
