Hello. I'm trying to use the TalkingClockI2S example with my ESP32, but when I connect everything, I hear unpleasant noises. I'm not sure what hardware is required, but I used a HW-104 hooked up to DAC_CHANNEL_1 (GPIO25).
The term "ESP32" encompasses a wide range of development boards and modules, each with distinct features and specifications. To provide effective assistance, it's essential to identify the specific ESP32 board you're using.
Labels and Markings: Many boards have model numbers or names printed directly on them. Look for identifiers like "ESP32-DevKitC," "NodeMCU-32S," or others.
Pin Configuration: Compare the pin layout of your board with standard pinout diagrams available online. This can offer clues about the board model.
If you have: the original packaging or datasheet, refer to them for model information.
- Provide Us Clear Documentation: Since we can’t see your project, share an annotated schematic (best) or a clear drawing of your setup. Pictures are welcome, but avoid using Fritzing diagrams as they are wiring diagrams, not schematics, and are not ideal for troubleshooting.
- Include Technical Details: If there is specific hardware involved, include links to technical information. There are often many versions of similar components, so precise details are essential. What version are you using?
- Reference Resources: For additional help, check out useful links and tutorials: Useful Links on Arduino Forum. Post links to your hardwares technical information.
- Obtain a copy: of the Arduino Cookbook and complete several of the projects. Many of them will help you achieve parts of your goals.

On the back, it says "ESP32S", although it is just a normal DevKit. However, some pins are missing, but DAC pins are still available.
The term "ESP32" encompasses a variety of modules and development boards, each tailored for specific applications. To provide accurate assistance, it's essential to identify the exact model you're working with. Here's a brief overview of some common ESP32 modules:
This is from the web.
- ESP32-WROOM-32: A widely used module featuring integrated Wi-Fi and Bluetooth capabilities, suitable for general-purpose applications.
- ESP32-S: Often refers to variants with specific features or form factors, potentially including integrated antennas.
- ESP32-D: Denotes modules that may have different pinouts or additional onboard components compared to standard ESP32 modules.
- ESP32-WROVER: Includes additional 8 MB SPI PSRAM, making it suitable for applications requiring more memory.
For a detailed comparison of these modules, you can refer to TechWithRita's article.
If you can provide the specific model number or a detailed description of your ESP32 board, I can offer more targeted assistance.
In that case, it is an ESP32-WROOM-32.
