This 44-Pin ESP32-S3 Expansion Board is a professional-grade power management and signal breakout solution specifically engineered for high-performance ESP32-S3 development modules. In 2025, as AIoT projects demand more memory and peripherals, this board serves as the essential foundation for stabilizing and scaling applications using N8R2 and N16R8 configurations. 
Product Description
The ESP32-S3 44P Expansion Board is designed to unlock the full hardware potential of the S3 chip. While standard 38-pin expansion boards often leave critical pins inaccessible, this 44-pin variant breaks out every available GPIO, including specialized pins for JTAG debugging, OPI PSRAM, and high-speed LCD/Camera interfaces. 
Engineered for industrial reliability, the board features an advanced power delivery system. It converts high-voltage DC input into rock-solid 3.3V and 5V rails, providing the high current (up to 2A) required by 8MB Octal PSRAM and peripherals like 5MP cameras or TFT touchscreens. Whether you are a business developing a smart retail kiosk or a single user building a complex Home Assistant hub, this board ensures your hardware remains stable and your wiring remains organized. 
Key Features
  • Complete 44-Pin Breakout: Specifically mapped for the ESP32-S3 footprint, ensuring no “hidden” GPIOs.
  • Industrial-Grade Power: Supports wide-range DC input via Type-C (5V) or DC Barrel Jack (6.5V – 24V).
  • GVS Prototyping System: Every GPIO is grouped with dedicated Ground (G) and Voltage (V) pins, allowing for direct “plug-and-play” with standard 3-pin sensors.
  • Dual-Row Header Design: Each signal is mirrored across two rows of pins, making it easy to connect a peripheral and a logic analyzer/oscilloscope simultaneously.
  • Integrated Protection: Features onboard capacitors and regulators to prevent “brown-out” resets during Wi-Fi/Bluetooth bursts or high AI processing loads.
  • Enclosure Ready: Includes four M3 mounting holes for secure installation in industrial control panels or custom project boxes. 
Usage Scenarios
  • Business / B2B: Rapid prototyping of Edge AI gateways, industrial vision systems (using 5MP cameras), and secure building automation controllers.
  • Advanced DIY / Makers: Developing high-end smart-home dashboards with LVGL displays, retro-gaming handhelds, or high-fidelity audio (I2S) processors.
  • Education: A robust, reusable platform for teaching advanced 32-bit embedded systems and AIoT architecture without the fragility of breadboards.
Q: Is this board compatible with the ESP32-S3 N16R8 version?

Yes. This 44-pin expansion board is optimized for the N16R8. It provides the reinforced power stability required for the 8MB Octal PSRAM to function correctly under heavy processing loads

Q: Why does this board have 44 pins while my ESP32-S3 module has 38?

The ESP32-S3 chip has a higher number of internal I/O pins than the standard ESP32. The 44-pin layout ensures that specialized pins (such as those used for high-speed PSRAM or Native USB) are accessible, even if your specific module doesn’t use all of them

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

No. The Type-C port on the expansion board is for power only. You must use the Type-C port located directly on your ESP32-S3 module for code uploading and serial monitoring

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

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

Q: Does it support the OV5640 5MP camera?

Yes. The expansion board provides the necessary high-current 3.3V and 5V lines to power both the camera and the S3 module during high-resolution JPEG encoding.

Q: Are the pin headers pre-soldered?

Yes, most professional versions of this board come with pre-welded/soldered headers, making it ready to use out of the box for single users and business engineers alike
