ESP32-S3 Development Board with 1.85" Round Display (360 x 360)

This is an ESP32-S3 development board with 2.4GHz Wi-Fi and Bluetooth BLE 5 support. Its 1.85" LCD has a 360 x 360 resolution and 262K colours, giving a sharp and vibrant display. It includes 16MB Flash and 8MB PSRAM and supports UART, I2C, and several IO interfaces, making it ideal for many different projects. There is also an audio decoder, microphone, QMI8658 6-axis sensor, RTC sensor, SD card slot, and battery recharge management module. The board is designed for fast HMI development, with optional capacitive touch control and support for GUI frameworks like LVGL. Please select whether you want the touch or no-touch option before adding to the cart! Features
