This high-performance Goouuu ESP32-S3-N16R8 development board is a professional-grade platform featuring the ESP32-S3-WROOM-1 module. In 2025, this 42-pin variant has become a favorite for engineers and makers due to its maximized I/O access and high-speed memory configuration. It is equipped with dual Type-C interfaces for versatile power and data management.
Product Description
The Goouuu ESP32-S3-N16R8 is built for power users who require the full potential of the ESP32-S3 silicon. Featuring an expanded 42-pin layout, this board breaks out more GPIOs than standard DevKitC models, allowing for complex multi-sensor integrations.
With 16MB of Flash and 8MB of Octal PSRAM, this board is specifically optimized for “Edge AI” tasks, including voice recognition and real-time image processing. The dual Type-C design provides ultimate flexibility: one port is dedicated to the USB-to-Serial bridge for easy programming, while the second port provides a direct Native USB connection to the S3 chip, enabling it to act as a high-speed USB device (HID, MIDI, or Disk Drive).
Key Features
  • Expanded 42-Pin Header: Provides additional GPIOs, including specialized pins for JTAG debugging or high-speed peripherals.
  • Dual Type-C Connectors:
    • UART Port: For stable firmware flashing and serial monitoring.
    • Native USB Port: Supports USB OTG, allowing the board to simulate keyboards, mice, or UVC cameras.
  • AI Acceleration: The Xtensa® LX7 core includes specialized vector instructions to speed up neural network inference.
  • Max Memory Spec (N16R8): 16MB Flash and 8MB Octal PSRAM handle large firmware and data-heavy applications with ease.
  • Goouuu Reliability: Known for high-quality PCB fabrication with excellent thermal dissipation and clear pin labeling.
Usage Scenarios
  • Business / Enterprise: Rapid prototyping of high-end IoT gateways, smart retail displays, and secure industrial controllers requiring 16MB of storage for complex UI/UX.
  • AI & Vision Research: Running lightweight TensorFlow Lite models for object detection or gesture control using the S3’s AI instructions.
  • Advanced Makers: Creating customized USB devices (HIDs), high-resolution audio players (I2S), or complex smart home hubs.
Q: Why does the Goouuu board have 42 pins instead of the usual 38?

The 42-pin layout breaks out additional internal signals of the ESP32-S3, providing users with more flexibility for hardware debugging (JTAG) and more available GPIOs for large projects.

Q: How do I access the full 8MB of PSRAM?

In your development environment (Arduino IDE or ESP-IDF), select the “ESP32S3 Dev Module” and ensure “PSRAM” is set to “OPI PSRAM”. If set incorrectly, your code may crash or only see 2MB of RAM.

Q: Can I power the board from both Type-C ports at the same time?

Yes, the board is designed with protection diodes. However, it is standard practice to use the “UART” port for power and data during development, and the “Native” port when testing USB device functionality.

Q: What is the difference between N16R8 and other versions?

“N16” stands for 16MB of Flash (storage), and “R8” stands for 8MB of PSRAM (volatile memory). This is the highest standard memory configuration available for the ESP32-S3-WROOM-1 module.

Q: Is this board compatible with MicroPython and CircuitPython?

Absolutely. The N16R8 configuration is highly recommended for CircuitPython because the large Flash and PSRAM allow for extensive libraries and complex scripts to run smoothly.

Q: Does it support 5V logic on the GPIO pins?

No. Like all ESP32 modules, the GPIO pins are 3.3V tolerant only. Applying 5V to any I/O pin will likely destroy the module.
