WaveShare ESP32-S3 LCD 3.16 Zoll 320×820 Display

The Waveshare ESP32-S3 LCD 3.16 is a compact development board featuring a 3.16-inch LCD with a resolution of 320×820 pixels. At its core is an ESP32-S3R8 with an Xtensa LX7 dual-core processor clocked up to 240 MHz, integrated 8.0 MB PSRAM, and 16.0 MB Flash memory – ideal for high-performance GUI applications. The display is driven via an RGB565 interface with an ST7701 driver, making it excellent for LVGL-based interfaces with smooth image rendering. For sensing and timing, it includes a QMI8658 6-axis IMU (Gyro + Acceleration) and a PCF85063 RTC; an RTC battery can be connected via an SH1.0 header. With 2.4 GHz Wi-Fi and Bluetooth 5 (LE), wireless communication is readily available, either through the onboard ceramic antenna or – via a solderable resistor – through an external antenna at the IPEX connector. An MX1.25 header allows for power supply from a 3.7 V Li-Ion cell (charging and discharging via USB-C), and a TF card slot provides additional storage. For development, UART, I2C, and USB headers are reserved, along with BOOT and RST buttons and an ON/OFF toggle switch.
