ESP32-S3 1.85in Round LCD Display Board WiFi + Bluetooth W/Battery

ESP32-S3 1.85 Inch Round LCD Display Board The ESP32-S3 1.85 inch round LCD display board is a compact development board built for smart displays, touch interfaces, voice projects, and connected electronics. It combines an ESP32-S3 microcontroller, a 360×360 round LCD screen, capacitive touch, Wi-Fi, Bluetooth BLE 5, audio input/output, and battery support into one ready-to-build platform. This board is a great choice for makers, students, hobbyists, and developers who want an ESP32 with display hardware already built in. Instead of wiring a separate screen, touch controller, audio board, and power circuit, this development board gives you a clean starting point for smart home controls, portable gadgets, AI voice demos, small HMI panels, and custom user interfaces. ESP32-S3 Round LCD Development Board for Smart Projects The onboard 1.85 inch round LCD display has a sharp 360×360 resolution and supports 262K colors, making it ideal for colorful menus, gauges, status screens, icons, animations, and LVGL-based GUI projects. The round display format gives finished projects a more polished look than a standard rectangular module, especially for dials, controllers, smart speaker displays, and compact touchscreen devices. With the ESP32-S3 dual-core processor running up to 240MHz, this board has the performance needed for responsive touch controls, wireless communication, graphics, audio features, and general embedded development. ESP32 With Display, Touch, Wi-Fi, and Bluetooth BLE 5 This ESP32-S3 display board supports 2.4GHz Wi-Fi 802.11 b/g/n and Bluetooth 5 LE, making it useful for connected projects that need app control, wireless data, smart home integration, or network communication. The onboard antenna keeps the design simple, while an IPEX connector is also available for projects that require an external antenna after the required onboard resistor change. The capacitive touch panel is controlled through an I2C interface and supports interrupt operation for smooth, responsive user input. This makes the board practical for touchscreen menus, buttons, sliders, settings screens, and other interactive controls. Built for AI Speech, Voice Control, and Smart Speaker Projects The ESP32-S3 1.85 inch round LCD development board includes onboard audio input and output hardware, making it well suited for AI speech interaction, voice control demos, and smart speaker-style projects. It can be used with offline voice models for customizable shortcut commands and can also be connected to online AI platforms such as GPT, DeepSeek, Doubao, and other large model services. The board includes audio codec hardware, microphone support, a speaker header, and the supporting components needed for voice-enabled embedded projects. This makes it a strong option for experimenting with voice assistants, voice-controlled devices, audio feedback, and interactive smart displays. Battery Included for Portable ESP32-S3 Projects This version includes a 3.7V LiPo 1000mAh battery, making it easier to start building portable projects. The board includes a battery recharge management module and an MX1.25 2-pin battery connector for a 3.7V lithium battery. It also includes a battery power switch, charge indicator, and USB Type-C port for convenient power and charging. Portable power support makes this ESP32-S3 round display board useful for handheld controllers, wearable-style displays, mobile sensor projects, battery-powered dashboards, and small interactive devices. Multiple Interfaces for Expansion and Prototyping The ESP32-S3-Touch-LCD-1.85C platform provides multiple expansion options, including UART, I2C, GPIO, a TF card slot, and a reserved 1.27mm 28-pin header. These interfaces make it easier to connect sensors, modules, storage, controls, and other peripherals while building custom ESP32-S3 applications. The board also includes an RTC chip for real-time clock functions, reset and boot buttons for development, and onboard power regulation with support for up to 3.3V 2A output from the MP1605GTF-Z power module.
