ESP32-S3 with 1.43 Inch AMOLED Touch Display and Metal Enclosure

The ESP32-S3 with 1.43-inch AMOLED Touch Display and Metal Enclosure is a compact development board from Waveshare based on the powerful ESP32-S3-PICO-1-N8R8 module. The Xtensa 32-bit LX7 Dual-Core processor operates at up to 240 MHz and, combined with 8 MB PSRAM and 8 MB Flash, provides ample computing power and memory for demanding applications. The circular 1.43-inch AMOLED display offers a resolution of 466 × 466 pixels with 16.7 million colors, delivering high contrast, wide viewing angles, and low power consumption. The capacitive touch function is implemented via the CST820 touch controller, while the CO5300 serves as the display driver. For wireless communication, 2.4 GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE) with an integrated onboard antenna are available. The board features a dual-microphone array with noise suppression and echo cancellation, enabled by the ES8311 audio codec and the ES7210 echo cancellation chip, making it ideal for high-quality voice processing. This makes the board particularly suitable for AI-driven voice interaction and integration with online LLM platforms. An MX1.25 connector for a 3.7V lithium battery allows for mobile operation, and the metal enclosure provides robust protection. Programming is done via the USB Type-C port and is supported by both ESP-IDF and Arduino IDE. Additional I2C, UART, and USB interfaces are available via reserved solder pads for external devices.
