ESP32-S3 Development Board with 3.49" Capacitive Touchscreen – DeepSeek AI Chat Box LCD Display 172×640 N16R8

Take your AI and IoT projects to the next level with the ESP32-S3 Development Board featuring a 3.49-inch Capacitive Touchscreen. This high-performance development kit is perfect for educators, hobbyists, makers, and developers looking to create interactive AI chat boxes, voice-controlled devices, or intelligent embedded systems.

Equipped with the ESP32-S3R8 dual-core 32-bit LX7 processor running at 240MHz, it supports 2.4GHz Wi-Fi and Bluetooth 5 (LE), making wireless connectivity fast and reliable. The 3.49-inch HD IPS capacitive touchscreen (172×640 resolution, 16.7M colors) provides crisp visuals for interactive applications, while QSPI and I2C interfaces simplify hardware communication.

Designed with AI voice interaction in mind, the board features a dual digital microphone array with noise reduction and echo cancellation, allowing for accurate speech recognition and near-field/far-field wake-up applications. It also includes a six-axis inertial measurement unit (QMI8658) for motion sensing, an RTC chip (PCF85063) for timekeeping, and a micro SD slot for flexible storage and media playback.

Additional features include customizable PWR and BOOT buttons, MX1.25 speaker port, lithium battery interface, and 22-pin through-hole pads for external module expansion. With full SDK support for ESP-IDF and Arduino, this board is beginner-friendly yet powerful enough for professional embedded applications.

Whether you’re building AI chat boxes, portable smart devices, or educational projects, this ESP32-S3 touch LCD development board gives you all the tools to innovate and interact with technology seamlessly.
