The ESP32-S2-Kaluga-1 is a development kit mainly designed for human-computer interaction applications. It includes one main-board and four extension boards that support: touch panel control, audio playback, LCD display and camera image acquisition, which allows users to interact with machines through sensory channels and body language.

User Guide available here.

Touch Panel Control

  • 14 touch sensors, three of which support distance detection(proximity mode)
  • Support acrylic panels up to 5mm
  • Wet hand operation
  • Mis-touch prevention; water rejection: ESP32-S2 can be configured to disable all touchpads automatically if multiple pads are simultaneously covered with water and to re-enable touchpads if the water is removed.

Audio Playback

  • Connect speakers to play audio
  • Use together with the Touchpanel to control audio playback and adjust the volume

LCD Display

  • LCD interface(8-bit parallel RGB, 8080, and 6800 interface)
  • Support display with ST7789 and ILI9341 driver
  • Support camera data real-time display on LCD screen

Camera Image Acquisition

  • Support OV2640 and OV3660 camera modules
  • 8/16-bits DVP image sensor interface
  • Clock frequency up to 40MHz
  • Optimized DMA transmission bandwidth for easier transmission of high-resolution images
