Description Waveshare ESP32-S3-Touch-LCD-7B 7inch Touch Display Dev Board 1024×600 is a low-cost, high-performance HMI development board built around the ESP32-S3-WROOM-1-N16R8. It supports 2.4GHz Wi-Fi and Bluetooth 5 LE, and combines 16MB Flash, 8MB PSRAM, and an onboard 7 inch capacitive touch LCD that can smoothly run GUI applications such as LVGL. This B version is the upgraded 1024 × 600 model, and compared with the standard 7 inch series it adds higher resolution, backlight brightness adjustment, and lithium battery voltage monitoring. With onboard CAN, RS485, I2C, TF card support, battery charging indicators, and USB connectivity, it is well suited to smart home panels, industrial terminals, and ESP32-S3 based HMI applications. Features ESP32-S3-WROOM-1-N16R8 module with dual-core Xtensa LX7 architecture, 16MB Flash, and 8MB PSRAM. 7 inch capacitive touch LCD with 1024 × 600 resolution and 65K colors. 5-point capacitive touch over I2C with interrupt support. Expanded peripheral support including CAN, RS485, I2C, UART, TF card, and USB. Integrated LVGL-ready display platform for touch GUI and HMI development. Backlight brightness adjustment support on the B version. Lithium battery voltage monitoring and charge status indication on the B version. Low-power control capability with flexible clock and module power supply settings for multi-scenario applications.
