Learn how the capacitive touch evaluation system, RSSK‑RA0L1, enables capacitive touch functionality on the RA0L1 microcontroller in a modern kitchen application. We highlight how touch buttons and sliders provide intuitive user interaction for common appliance controls. 

Learn about the Capacitive Touch Evaluation System for RA0L1 (RSSK‑RA0L1), its key features, and how it supports ultra‑low‑power capacitive‑touch development. We will walk through the quick‑start guide document, unbox the hardware, and show how to set up the development environment and generate a project. A hands‑on demo highlights the RA0L1 MCU’s capacitive‑touch performance and demonstrates how the board helps developers begin evaluating the device quickly.

静电电容触控感应组件“CTSU2”，强化抗噪性能，且支持“有源屏蔽”的功能，能有效的提高自感触摸按键的防水性能。本方案配置了一个 GND 屏蔽和一个有源屏蔽。可以比较不同屏蔽方法的防水性能。

This video shows a 2D gesture demo using a Renesas Capacitive Touch MCU.

3D gesture demo applies Renesas' capacitive touch solution to realize an HMI that detects gesture motions (up and down, left and right, and forward and back) of a hand in three-dimensional space.

This video introduces a smart wake-up solution that can reduce standby current consumption by more than 90% compared to conventional products. The hardware uses the RX140 capacitive touch evaluation system and touchless button demo.

Wood, stone, cloth, and paper may be used as cover panels of capacitive touch sensors.

This capacitive touch solution makes it possible to revolutionize design in a restriction-free (material-free and design-free) environment. In recent years, home electronics and other products have been adopting capacitive touch interfaces to improve design and durability. The demand for better demand is becoming especially strong. These solutions enable wood, stone, cloth, paper, and other materials that were previously not used for operating panels of electronic devices, to be used as cover panels for capacitive touch sensors instead of traditional resin materials such as glass or acrylic.
