ESP32-S3 development board with touch LCD display 1,54"
Waveshare development board, based on a high-performance dual-core microcontroller ESP32-S3. The module is enclosed in a specially designed case and is equipped with an IPS LCD touch screen with a diagonal of 1.54". It features integrated microphones, an IMU motion sensor, and support for Wi-Fi and Bluetooth 5 connectivity, making it an ideal solution for HMI projects, IoT, voice interaction, and artificial intelligence applications.
Key features:
- High-performance dual-core processor ESP32-S3R8.
- Integrated Wi-Fi 2,4 GHz and Bluetooth 5 (LE) connectivity with an onboard antenna.
- Capacitive touch display IPS LCD 1,54" with a resolution of 240 x 240 pixels and a color palette of 262K.
- Memory: 512 KB SRAM, 384 KB ROM, 8 MB PSRAM, and 16 MB external Flash memory.
- Built-in dual microphones and audio chips (ES7210, ES8311, NS4150B) with hardware echo cancellation.
- 6-axis IMU motion sensor QMI8658 (3-axis accelerometer and 3-axis gyroscope).
- Slot for TF memory card for easy media storage and data logging.
- Battery connector Li-Po 3,7 V (MX1.25) with an integrated charging management circuit.
- USB Type-C interface for convenient programming and powering the module.
Small size, unlimited possibilities
The device is perfect for creating smart controllers and building modern human-machine interfaces (HMI). Thanks to the battery connector, the board can operate independently, and the default software allows for, among other things, running AI-based conversations, audio and video playback, or simple arcade games.
