WAVESHARE ESP32-S3 1.83-Inch Touch LCD Development Board With 240x284 Resolution Onboard Audio Codec Chip, Version: Without Battery

Overview & Features

. The ESP32-S3-Touch-LCD-1.83 is a high-performance, highly integrated microcontroller development board. In a compact form factor, the board integrates a 1.83-inch capacitive LCD screen, a highly integrated power management chip, a six-axis sensor (three-axis accelerometer and three-axis gyroscope), RTC, and a low-power audio codec chip, facilitating development and embedding into products. Equipped with ESP32-S3R8 high-performance Xtensa 32-bit LX7 dual-core processor, with a clock speed up to 240MHz. Supports 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE), with an onboard antenna. Built-in 512KB SRAM and 384KB ROM, stacked 8MB PSRAM and external 16MB Flash. Uses a Type-C interface, improving user convenience and device compatibility. Onboard 1.83-inch capacitive touch LCD screen, 240 × 284 resolution, 65K colors. Built-in ST7789P driver chip and CST816D capacitive touch chip, communicating via SPI and I2C interfaces respectively, without occupying excessive interface pins. Onboard QMI8658 six-axis inertial measurement unit (3-axis acceleration, 3-axis gyroscope), capable of detecting motion posture, step counting, and other functions. Onboard PCF85063 RTC chip, connected to the battery via AXP2101 for uninterrupted power supply. Onboard PWR and BOOT side buttons with customizable functions, facilitating custom function development using the buttons. Onboard JST 1.2mm lithium battery charging and discharging interface. Provides 1 I2C, 1 UART, and 1 USB solder pads for external devices and debugging, allowing flexible configuration of peripheral functions.
