This 44-Pin GPIO IoT Expansion Board is a professional-grade interface solution specifically engineered for the ESP32-S3 series of development boards. In 2025, as AIoT (AI + IoT) applications demand more memory and more I/O, this expansion board serves as the essential foundation for stabilizing high-density projects using the ESP32-S3 N8R2 or N16R8 modules.
Product Description
The 44-Pin ESP32-S3 Expansion Board is a robust breakout system designed to solve the physical and electrical challenges of advanced IoT prototyping. While standard ESP32 boards often cover the power rails on a traditional breadboard, this expansion shield breaks out all 44 pins into a spacious, clearly labeled layout.
It features an industrial-grade power management system that accepts a wide range of DC inputs, converting them into stable 3.3V and 5V rails. This is critical for ESP32-S3 modules running 8MB Octal PSRAM, which can be sensitive to the slight voltage fluctuations common in USB-only power setups. Whether you are building a smart retail kiosk with face detection or an industrial sensor gateway, this board provides the electrical protection and mechanical stability required for 24/7 operation.
Key Features
  • Full 44-Pin Access: Specifically mapped for the ESP32-S3-WROOM-1 footprint, ensuring every GPIO—including high-speed SPI and JTAG pins—is accessible.
  • Dual-Channel Power Input: Supports power via USB Type-C (5V) or a DC Barrel Jack (accepting 6.5V to 24V), providing flexibility for field deployments.
  • GVS Prototyping Layout: Standardized Ground-Voltage-Signal (GVS) pin groupings allow for “plug-and-play” connectivity with 3-pin sensors, servos, and actuators.
  • Industrial Stability: Onboard high-efficiency buck regulators provide up to 2A of current, easily powering external peripherals like 5MP cameras, TFT touchscreens, and relays.
  • Breadboard Eliminator: Removes the risk of loose wires or high-resistance connections that cause “ghost” resets in Wi-Fi and Bluetooth projects.
  • Integrated Mounting Holes: Includes 4x M3 mounting holes for secure installation in industrial control boxes or custom enclosures.
Usage Scenarios
  • Business & B2B: Rapid prototyping of Edge AI devices, such as smart occupancy sensors, industrial voice-command modules, and secure gateway controllers.
  • Advanced DIY/Makers: Building high-end home automation hubs (Home Assistant/ESPHome) that require simultaneous use of a camera, SD card, and multiple I2C/SPI sensors.
  • Educational Institutions: A durable, reusable platform for teaching advanced embedded systems and AIoT development without the need for soldering.
Q: Is this board compatible with the ESP32-S3 N16R8 specifically?

Yes. This 44-pin board is specifically designed to match the pinout of the S3-N16R8. It provides the reinforced power stability required for the 8MB Octal PSRAM to function at full speed without data corruption.

Q: Why does it have 44 pins when many ESP32 boards have 38?

The ESP32-S3 chip has a higher number of internal I/O pins than the original ESP32. The 44-pin layout ensures that no pins are “orphaned” or hidden under the module, giving you access to specialized functions like JTAG debugging and native USB OTG.

Q: Can I program the ESP32-S3 through the expansion board's USB port?

No. The Type-C port on the expansion board is typically for power delivery only. You must use the Type-C port located directly on the ESP32-S3 module for data transfer and code uploading.

Q: Can I use this for battery-powered applications?

Yes. You can connect a 7.4V or 11.1V Li-Po battery to the DC Jack or the Vin pins to provide portable power for mobile IoT projects.

Q: Are the headers pre-soldered?

Most professional-grade Goouuu expansion boards come with pre-soldered female headers for the ESP32-S3 and male headers for the GVS pins, making it ready for immediate use.

Q: Is it compatible with the OV5640 5MP Camera?
Yes. The expansion board provides the necessary current to power both the camera and the S3 module during high-resolution JPEG encoding, which is difficult to achieve with standard USB power alone.
