Touch-Sensor Development Kit for ESP32

The ESP32-Sense Kit is a new touch-sensor development kit produced by Espressif Systems. It can be used for evaluating and developing the touch-sensing functionality of ESP32. The ESP32-Sense Kit consists of one motherboard and several daughterboards. The motherboard is made up of a display unit, a main control unit and a debug unit. The daughterboards can be used in different application scenarios, since the ESP32-Sense Kit supports a linear slider, a duplex slider, a wheel slider, matrix buttons, and spring buttons. Users can even design and add their own daughterboards for special use cases. The photo provides an overview of the ESP32-Sense Kit. The wheel slider, linear slider, duplex slider, motherboard, spring buttons, and matrix buttons, are shown in a clockwise direction.

The ESP32 SoC offers up to 10 capacitive I/Os that detect changes in capacitance on touch sensors due to finger contact or proximity. The chip’s internal capacitance detection circuit features low noise and high sensitivity. It allows users to use touch pads with smaller area to implement the touch detection function. Users can also use the touch panel array to detect a larger area or more test points.

The follow related resources are available to support ESP Sense Kit:

  • ESP32 t=Touch-Sensor Design: The reference design manual of the ESP32 touch-sensing system.
  • ESP32-Sense Project: Contains programs for the ESP32-Sense Kit, which can be downloaded to the development board to enable the touch-sensing function.
  • ESP-IDF: The SDK for ESP32. Provides information on how to set up the ESP32 software environment.
  • ESP-Prog: The ESP32 debugger.
