Waveshare ESP32-S3 1.28-Inch Dual IPS LCD AIoT Development Board

You can program it using the Arduino IDE with the ESP32-S3 board package installed or directly with Espressif's ESP-IDF framework. Connect the board via the provided USB Type-C cable, select the correct COM port, and choose 'ESP32S3 Dev Module' as your target. The onboard boot and reset buttons facilitate entry into download mode for firmware flashing. Ensure you have the necessary LCD and audio driver libraries from Waveshare's GitHub repository.

Yes, the dual 1.28-inch IPS LCDs can be controlled independently. They are connected via separate SPI or parallel display interfaces (check the pinout diagram). You will need to initialize two display objects in your code, referencing their distinct GPIO pins for chip select (CS) and data/command (DC). The ample 8MB PSRAM on the board is crucial for buffering graphics for both screens simultaneously without performance degradation.

The ES8311 codec handles digital-to-analog conversion for audio output to the speaker, while the ES7210 manages analog-to-digital conversion for the microphone input. To use it, you must include the appropriate I2S audio library in your ESP-IDF or Arduino project. Configure the I2S peripheral with the correct sample rate and bit depth, then use API calls to record from the microphone or play audio files. The speaker header accepts the included 2W speaker for playback.

Connect a standard 3.7V Li-ion battery to the dedicated two-pin battery header. The onboard TP4054 charging circuit will manage charging via USB. Battery life depends entirely on your application's power profile. Utilize the ESP32-S3's deep sleep modes (consuming ~10µA) when the displays and wireless are off to maximize longevity. For active use with screens and Wi-Fi on, expect currents in the 100-300mA range, requiring a suitably sized battery (e.g., 1000mAh) for extended operation.
