This 44-Pin GPIO IoT Expansion Board is a professional-grade breakout and power management solution specifically engineered for the ESP32-S3 series. Designed to accommodate the high-density N8R2 and N16R8 modules, this board is the ideal foundation for developers building memory-intensive AIoT applications in 2025.
Product Description
The 44-Pin ESP32-S3 Expansion Board is a robust interface bridge designed to unlock the full potential of the S3’s dual-core processor and its advanced AI vector instructions. While standard 38-pin boards limit access to the S3’s extensive I/O, this 44-pin variant breaks out every available signal, including specialized pins for JTAG debugging, OPI PSRAM interfaces, and high-speed peripherals.
Engineered for industrial-grade reliability, the board features an enhanced power delivery system. It converts high-voltage DC input into stable, low-noise 3.3V and 5V rails, ensuring that power-hungry components like high-resolution cameras, touchscreens, and motor drivers operate without causing system “brown-outs.” Whether you are prototyping a smart retail kiosk or a secure industrial gateway, this board provides the physical stability and electrical protection required for professional deployment.
Key Features
  • Maximized I/O Access (44-Pin): Specifically designed for the ESP32-S3-WROOM-1 series, breaking out all pins for N8R2 (2MB PSRAM) and N16R8 (8MB PSRAM) configurations.
  • Industrial Voltage Regulation: Integrated high-efficiency buck/boost regulators supporting wide-range DC input via Type-C or DC Barrel Jack.
  • AIoT Optimized: Provides stable current overhead for S3-specific AI tasks like voice recognition and facial detection.
  • Dual-Row Signal Pins: Every GPIO is mirrored across two rows of headers, allowing for simultaneous connection of a sensor and a logic analyzer/debug tool.
  • GVS Prototyping Layout: Standardized Ground-Voltage-Signal (GVS) pin groupings for easy “plug-and-play” with 3-pin sensors and servos.
  • Secure Mounting: Features 4x M3 mounting holes for permanent installation inside machinery or 3D-printed project enclosures.
Usage Scenarios
  • Business & B2B: Rapid prototyping of Edge AI gateways, smart office occupancy sensors, and industrial automation controllers.
  • Professional Engineering: Developing HMI (Human-Machine Interface) systems using the S3’s high-speed SPI/LCD interfaces and 8MB PSRAM.
  • Advanced DIY/Makers: Building high-end smart home hubs (Home Assistant) or customized USB HID devices (Macro-pads, Flight Sim controllers).
Q: Does this board support the ESP32-S3 N16R8 version specifically?

Yes. This 44-pin expansion board is specifically designed to match the pinout of the N16R8 module. It provides the stable power required by the 8MB Octal PSRAM, which is more sensitive to voltage drops than standard RAM

Q: Why choose 44-pins over the standard 38-pin version?

The ESP32-S3 chip has more internal I/O than previous generations. The 44-pin layout ensures that “hidden” GPIOs used for high-speed PSRAM or JTAG debugging are accessible for your project

Q: Can I power the board with a 24V industrial power supply?

Most models of this expansion board include a wide-voltage regulator (DC 6.5V–24V). Please check the specific voltage rating on your board’s DC Jack before connecting

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 programming

Q: Is it compatible with the OV5640 5MP Camera?

Yes. The expansion board provides the high current needed for the 5MP camera and the PSRAM buffering required by the S3 to process high-resolution images.

Q: Does the board come with the ESP32-S3 module included?

This listing is for the Expansion Board (Baseboard) only. The ESP32-S3-WROOM-1 (N8R2/N16R8) module must be purchased separately or as part of a bundled kit.
