Waveshare ESP32-S3 1.46-Inch Round Display Dev Board w/ IMU, Speaker & Mic

The board is fully compatible with the official Espressif ESP-IDF framework, the Arduino Core for ESP32, and MicroPython. You can use PlatformIO or the Arduino IDE with the ESP32-S3 board package installed. The USB-C port provides a serial CDC connection for flashing code and serial debugging directly from your development environment without needing an external programmer.

You can power the board via the onboard MX1.25 2-pin connector using a standard 3.7V lithium polymer (LiPo) battery. Runtime depends heavily on your code's power management. Utilize the ESP32-S3's deep sleep modes, controlled via GPIO or a timer, to minimize current draw to microamps. With active display and wireless radios on, expect higher milliamp consumption, so battery capacity (e.g., 1000mAh) and sleep duty cycle are key factors for determining operational lifespan.

Yes, the integrated digital MEMS microphone provides audio input suitable for basic voice capture and processing. For advanced voice recognition, you would implement algorithms using the ESP32-S3's processor or send audio data to a cloud service via Wi-Fi. The onboard speaker allows for audio feedback. You'll need to use appropriate audio libraries in ESP-IDF or Arduino to handle I2S communication for the microphone and PWM or DAC output for the speaker.
