Add plenty of touch sensors to your next microcontroller project with this easy-to-use 8-channel capacitive touch sensor board breakout, starring the CAP1188. This chip can handle up to 8 individual touch pads, and it has a very nice feature that makes it stand out to us: the 8 on-board LEDs will light up when it fires the corresponding touch sensor to help you correct your sensor setup.

The CAP1188 has supported both I2C and SPI, so it is easy to use with any microcontroller. If you use I2C, you can select one of 5 addresses, for a total of 40 capacitive touch pads on one I2C 2-wire bus. Using this chip is much easier than doing capacitive sensing with analog inputs: it handles all the filtering for you and can be configured for more/less sensitivity.

Features:

• Input Voltage : 23Volt – 5Volts DC.
• Sensitivity can adjust by the capacitance(0~50pF).
• Provides direct mode toggle mode by pad option(TOG pin).
• After power-on have about 0.5sec stable-time, during the time do not touch the keypad, and the function is disabled.
• Auto calibration and Re-calibration period is about 4.0 sec when the key has not be touched.

Package Includes:
