This high-performance ESP32 DevKitC variant is a professional-grade development platform featuring the ESP32-WROVER-B (N4R8) module. It is uniquely configured with the modern Type-C USB interface and the industry-standard CP2102 serial chip, making it a reliable choice for both individual engineers and commercial IoT product teams in 2025.
Product Description
The ESP32 DevKitC WROVER-B N4R8 is engineered for memory-intensive IoT applications. While standard ESP32 boards offer limited internal memory, this “N4R8” version provides a massive 8MB of External PSRAM alongside 4MB of SPI Flash. This extra RAM is critical for tasks like high-resolution image processing (ESP32-CAM projects), complex web servers, voice recognition, and AIoT edge computing.
The board features the CP2102 USB-to-UART bridge, known for its superior driver stability and higher data transfer speeds compared to cheaper alternatives. The inclusion of a Type-C interface ensures compatibility with modern hardware and improved durability for frequent programming cycles.
Key Features
  • Enhanced Memory: 8MB PSRAM enables large data buffering and multitasking that standard modules cannot handle.
  • Dual-Core Power: Powered by the Xtensa® 32-bit LX6 dual-core processor, adjustable from 80MHz to 240MHz.
  • Modern Connection: Type-C port for modern cable compatibility and more robust power delivery.
  • Industrial Stability: The CP2102 chip provides “plug-and-play” serial communication on Windows, macOS, and Linux.
  • Breadboard Friendly: Slim 38-pin design fits standard breadboards while leaving accessible holes for wiring.
Usage Scenarios
  • For Individual Makers: Ideal for smart home hubs (Home Assistant), DIY retro gaming consoles, and learning MicroPython or Arduino.
  • For Business/Enterprise: Used for rapid prototyping of industrial gateways, smart security cameras, and environmental monitoring systems where reliability and high memory are required.
Q: Why choose the WROVER-B N4R8 over the standard WROOM module?

The WROVER-B N4R8 includes 8MB of PSRAM, whereas WROOM modules have none. If your project involves a display, camera, or complex web interface, the PSRAM is essential to prevent “out of memory” crashes.

Q: Do I need to install special drivers for the Type-C port?

The board uses the CP2102 chip. Most OS versions (Win 10/11, macOS) will recognize it automatically. If not, drivers are available on the Silicon Labs website.

Q: Can I use this board with the Arduino IDE?

Yes. Select “ESP32 Wrover Module” in the Board Manager and ensure “PSRAM” is set to “Enabled” in the Tools menu to utilize the full 8MB.

Q: Is the board 5V tolerant?

No. While it can be powered by 5V via USB or the Vin pin, the I/O pins operate at 3.3V. Connecting 5V signals directly to GPIO pins will damage the processor.

Q: How do I enter "Flash Mode" if it isn't recognized?

Hold the BOOT button, press and release the EN (Reset) button, then release the BOOT button. This manually triggers the bootloader for firmware uploading.
