rKey Overview

The rKey Capacitive Touch Key Module is an easy way to add user input to your project.

• Auto-calibration
  • The rKey auto-calibrates on power-up to maximize effectiveness through whatever panel material and thickness is used (up to 0.4”/10mm).
• Durable
  • Because there are no moving parts, and the rKey can be mounted behind a sealed panel, possibility of physical damage is at a minimum.
• Low Power
  • Using break-through technology, the rKey uses extremely little power to detect touches. At 5.0V, less than 80 μA are needed.
• Separate LED control
  • To have complex visual feedback, the LED on-board the rKey can be controlled separately by a microcontroller. For simple touch feedback, the rKey output can be connected to the LED input.
