Capacitive Touch Remote Controller

Overview

Description

Slim, minimalist designs without physical buttons are increasingly appealing in consumer electronics and smart home applications. As households adopt more connected devices, an interoperable controller that can manage smart lights, TVs, sound systems, and more becomes essential.

This capacitive touch remote offers customizable gestures, swipes, and controls, consolidating multiple functions into one intuitive device. Its button-free design reduces mechanical points of failure, simplifies cleaning, and delivers versatile input through touchpads, sliders, and virtual buttons.

System Benefits:

  • Low-power system design extends battery life and usage time with energy-efficient components.
  • Consolidated BOM minimizes external components (e.g., clocks, level shifters, regulators), enabling a compact form factor.
  • Capacitive touch MCU supports flexible gesture inputs, including wheels, buttons, sliders, and swipes.
  • Certified Bluetooth® Low Energy (LE) modules ensure reliable connectivity and compliance with Bluetooth 5.1 and 5.3 standards.
  • Optional haptics driver adds tactile feedback for a more intuitive and engaging user experience.
