5. Einrichtungsanweisungen

Befolgen Sie diese Schritte für die Ersteinrichtung:

1. Lautsprecher anschließen: If using the included speaker, connect its MX1.25 connector to the corresponding header (No. 6 in Figure 4.1) on the development board.
2. Stromanschluss: Connect the development board to a power source using a Type-C USB cable. The Type-C port (No. 14 in Figure 4.1) also serves as the data interface for programming and debugging.
3. Batterie (optional): For portable applications, connect a 3.7V Lithium battery to the MX1.25 battery header (No. 16 in Figure 4.1). The board's power management IC will handle charging and discharging.
4. Erstes Einschalten: Press the PWR button (No. 4 in Figure 4.1) to power on the device. The AMOLED display should illuminate.
5. Entwicklungsumgebung: For programming, refer to the online tutorial for setting up your preferred development environment (e.g., ESP-IDF, Arduino IDE).

6. Bedienungsanleitung

Basic operation of the ESP32-S3 Development Board:

• Ein-/Ausschalten: Use the PWR button (No. 4) to turn the device on or off.
• Display-Interaktion: The 1.75-inch AMOLED display is capacitive touch-enabled. Interact with on-screen elements by tapping or swiping as programmed.
