The Goouuu ESP32-S3 Expansion Board is a professional-grade breakout shield designed to maximize the utility of ESP32-S3 development modules (specifically the 38-pin or 42/44-pin variants). In 2025, it is a staple for both industrial rapid prototyping and complex DIY IoT projects, offering a secure alternative to unstable breadboard connections.
Product Description
This expansion board serves as a robust foundation for the ESP32-S3-WROOM-1 series. It converts high-density pin headers into accessible, dual-row 2.54mm male/female headers or screw terminals, depending on the specific model variant. Built with high-quality PCB materials and an immersion gold finish, it ensures long-term signal stability even in environments with physical vibrations or temperature fluctuations.
The board often features multiple power input options (Type-C, Micro-USB, and DC Jack) to provide stable 5V and 3.3V rails for high-power peripherals like cameras, displays, or motor drivers that standard USB ports might fail to sustain.
Key Features
  • Dual-Row Header Breakout: Most Goouuu models expand one GPIO pin into two rows of headers, making it easy to bridge multiple sensors to a single pin.
  • Versatile Power Inputs: Supports Type-C, Micro-USB, and a DC Barrel Jack (6.5V–9V or up to 30V depending on the model) for flexible power delivery.
  • Onboard Power Indicators: Integrated LED indicators for real-time monitoring of power status.
  • Mounting Options: Includes fixed 3mm mounting holes for permanent installation inside project enclosures or industrial control panels.
  • Breadboard Eliminator: Removes the need for repeated soldering or messy jumper wire setups during iterative testing.
Usage Scenarios
  • Business/Commercial: Rapidly test hardware for industrial automation gateways or environmental monitoring hubs before final PCB manufacturing.
  • Single User/DIY: Ideal for “Smart Home” projects requiring high-current peripherals, such as driving LED strips (WS2812B) or OLED/TFT displays.
  • Educational Labs: Simplifies student hardware setups by providing clearly labeled pins and reducing accidental short circuits.
Q: Can I program my ESP32-S3 through the expansion board's USB ports?

No. In most Goouuu expansion board models, the USB ports are for power input only. To upload code or use the Serial Monitor, you must use the USB/Type-C port located directly on the ESP32-S3 development board itself.

Q: What is the benefit of the dual-row header design?

It allows you to connect a peripheral to a pin and still have an open terminal for a logic analyzer, multimeter probe, or an additional parallel sensor without messy splicing.

Q: Is it safe to use the DC Barrel Jack?

Yes, provided you adhere to the specified voltage range (typically 6.5V–9V for basic models, up to 30V for premium models). Always verify your specific board’s limit to avoid damaging the onboard voltage regulator.

Q: Does it support both 3.3V and 5V modules?

The expansion board is designed for 3.3V logic ESP32-S3 modules, but it provides both 5V and 3.3V power outputs to support different types of external sensors.

Q: Can I mount this board inside an enclosure?

Yes. The board features pre-drilled 3mm mounting holes at the corners, making it easy to secure with standoffs or screws into a project box.
