Waveshare ESP32-S3-Touch-LCD-1.9 is the touch-enabled version of Waveshare's compact 1.9inch ESP32-S3 display board. It combines a 170320 LCD, capacitive touch, ESP32-S3R8, 16MB Flash, QMI8658 6-axis IMU, TF card slot, and 3.7V lithium battery support in a compact board that is also compatible with Pico headers. This makes it a good fit for portable UI, compact IoT terminals, touch-enabled dashboards, and ESP32-S3 prototyping projects that need both local interaction and wireless connectivity.

Features

ESP32-S3R8 onboard: Xtensa 32-bit LX7 dual-core processor up to 240MHz with Wi-Fi and Bluetooth 5 LE support.
1.9inch touch LCD: 170320 resolution, 262K colors, and CST816 capacitive touch on the touch version.
Touch version-specific hardware: This SKU is the ESP32-S3-Touch-LCD-1.9 version, not the non-touch board.
Pico header compatibility: Official materials note that the interface is compatible with the Pico header, which helps with selected Raspberry Pi Pico HAT expansion.
Battery-ready design: Includes an MX1.25 battery header and charge indicator for 3.7V lithium battery use.
Storage and motion support: Combines a TF card slot and QMI8658 IMU for richer embedded projects.
