Wave ESP32-S3 with 7" Capacitive Touch Display

The Wave ESP32-S3 with 7" Capacitive Touch Display is a powerful development board designed for HMI (Human-Machine Interface) and IoT applications. Featuring an Xtensa 32-bit LX7 dual-core processor with a clock speed of up to 240MHz, it delivers high performance for demanding tasks. Equipped with 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE), it ensures seamless wireless connectivity. The onboard 7-inch capacitive touch screen, with 800×480 resolution and 65K colors, supports smooth GUI rendering, such as LVGL, and offers 5-point touch control via I2C.



With 8MB PSRAM, 8MB Flash, and integrated peripheral interfaces including CAN, RS485, I2C, and a TF card slot, this board is well-suited for complex projects. Its onboard antenna enhances wireless performance, while features like flexible clock settings and independent power supply control enable efficient power management for diverse applications.
