Waveshare ESP32-S3 Touch LCD 2.0" (with camera) specifications

The Waveshare ESP32-S3-Touch-LCD-2 is a 2-inch touch display board with a camera socket on the back — a combination that makes it a small camera viewer, QR-code scanner or AI-vision front end, not just a display.

The 240×320 panel uses an ST7789T3 controller with 262K colours and reaches about 530 cd/m². Touch is handled by a CST816D on I2C. The 24-pin camera connector accepts OV2640 and OV5640 modules, and the ESP32-S3R8's 8 MB of PSRAM gives it room for camera frames.

A QMI8658 6-axis IMU, a microSD slot and a lithium battery charger round it off, with 16 MB of flash and a USB-C port for power, download and debugging. LCD Ultra Pro supports the board in portrait and landscape; the exported Arduino project contains the display and touch driver, so you can concentrate on the interface around the camera.

Free GPIOs and connectors

These GPIOs are not used by the display, touch or on-board peripherals, so you can wire your own sensors, buttons or relays to them.

Good to know before you start

  • The camera uses most of the remaining pins: only GPIO 3 and 5 are free besides BOOT and UART0.
  • Rotation to 90° (320×240) is supported.
  • Camera frames need PSRAM — keep the UI light when streaming images.
  • Waveshare recommends FAT32 microSD cards of 32 GB or less.

What it is good for

  • •Camera viewers and QR-code scanners
  • •AI-vision prototypes with a local display
  • •Portable handheld tools
  • •Small touch dashboards
