ESP32-S3 2.8 Inch Display Voice Chat AI Module Price in Bangladesh

The ESP32-S3 2.8 Inch Display Voice Chat AI Module is an integrated development platform designed for smart-display, voice-interaction, IoT, and AI-oriented projects. It combines an ESP32-S3 dual-core processor, 2.8-inch color TFT display, capacitive touch interface, wireless connectivity, microphone, and speaker support in a compact development board.

The ESP32-S3 uses a dual-core Xtensa LX7 processor capable of operating at up to 240MHz. The module also provides 2.4GHz Wi-Fi and Bluetooth connectivity, making it suitable for connected embedded applications.

The integrated 2.8-inch TFT display provides a 240 × 320 pixel resolution and uses an ILI9341V display controller on commonly documented versions. Models such as the ES3C28P include capacitive touch, allowing users to interact directly with graphical interfaces.

One of the key features of this board is its audio capability. A built-in microphone can capture voice input, while an external speaker can be connected for audio output. This makes the module suitable for voice-controlled interfaces, AI assistants, smart terminals, and interactive electronics.

The board supports Xiaozhi AI voice-chat functionality, providing a ready-made platform for experimenting with AI voice interaction. Depending on the firmware and software implementation, the device can connect to AI services and provide spoken interaction while displaying information on the screen.

The module is also designed with development and expansion in mind. It includes interfaces such as I²C and UART, a Micro TF card slot on documented versions, and support for an external 3.7V lithium battery with integrated charging management.

This combination of display, touch, wireless connectivity, audio, and processing makes the board considerably more versatile than a basic ESP32 development board. It can be used to build interactive dashboards, smart control panels, AI terminals, voice assistants, IoT interfaces, and educational projects.
