The ESP32-DevKitC Development Board with WROVER Module and CP2102 chip is a high-performance, advanced prototyping platform designed for complex Internet of Things (IoT), multimedia, and embedded applications requiring expanded memory capacity. This board integrates the powerful ESP32-D0WDQ6 chip with additional PSRAM (external RAM), making it ideal for graphics-intensive projects, large data buffering, and sophisticated application development.
Product Description
The ESP32-DevKitC with the WROVER module is an enhanced version of the standard DevKitC, specifically designed for applications that exceed the memory limitations of standard WROOM modules. It features the ESP32 System-on-Chip (SoC), which offers dual-core processing up to 240 MHz, along with integrated 2.4 GHz Wi-Fi (802.11 b/g/n) and dual-mode Bluetooth connectivity.
The key advantage of the WROVER variant is the inclusion of 4MB of integrated PSRAM (Pseudo-Static RAM) alongside the standard 520KB SRAM. This substantial memory boost allows developers to tackle larger, more memory-intensive projects, such as running complex display drivers, handling large data streams, or running multiple network protocols simultaneously without memory constraints.
The board utilizes the reliable Silicon Labs CP2102 USB-to-UART bridge chip, ensuring stable communication and easy programming via the universally compatible Micro USB interface. The design is breadboard-friendly, breaking out all essential GPIO pins for easy integration with sensors, actuators, and peripherals, serving both individual makers with ambitious projects and businesses developing professional, high-demand solutions.
Key Features
  • Expanded Memory (PSRAM): Features 4MB of additional PSRAM (Pseudo-Static RAM) on the WROVER module, enabling larger application memory allocation.
  • Powerful Dual-Core Processing: Utilizes the Tensilica LX6 32-bit dual-core microprocessor, adjustable up to 240 MHz.
  • Integrated Connectivity: Built-in 2.4 GHz Wi-Fi and dual-mode Bluetooth (Classic and BLE) capabilities.
  • Reliable USB Interface: Uses the robust CP2102 USB-to-TTL serial converter chip for stable data links and easy firmware uploads.
  • Rich Peripheral Set: Exposes interfaces like UART, SPI, I²C, I²S, PWM, ADC, DAC, SD card interface, and capacitive touch sensors.
  • Flexible Development: Compatible with multiple development environments, including the Arduino IDE and the robust Espressif IoT Development Framework (ESP-IDF).
  • Security: Supports secure OTA (Over-The-Air) updates, WPA/WPA2/WPS security, and hardware encryption acceleration.

Usage
The WROVER board is used similarly to the standard DevKitC, but typically in projects demanding more memory resources:
  1. Power Up: Connect the board to your PC using a Micro USB cable.
  2. Driver Installation: The CP2102 drivers are typically installed automatically by modern operating systems. If needed, official drivers can be obtained from the Silicon Labs website.
  3. Set up the IDE: Configure your development environment (e.g., Arduino IDE) and ensure you select the correct board profile that specifies “WROVER Module” to correctly enable and utilize the 4MB PSRAM in your code.
  4. Programming: The onboard circuitry handles automatic bootloader entry. Upload your code directly from the IDE.
  5. Prototyping: Use the standard 2.54mm pitch pins to interface with breadboards and other components, leveraging the extra RAM for advanced projects such as web servers with graphical interfaces or data-logging applications.
Q: What is PSRAM and how do I use it?

PSRAM (Pseudo-Static RAM) is extra volatile memory (4MB) used to store large temporary data structures, frame buffers for displays, or large strings/arrays that won’t fit in the standard 520KB SRAM. You must enable it in your IDE settings (e.g., “Huge App” partition scheme in Arduino IDE) to use it.

Q: Is this board better than the WROOM-32D version?

The WROVER version is “better” if your project specifically needs more RAM. For simple projects that fit within the standard memory limits, the WROOM version is sufficient and functionally identical in terms of CPU power and features.

Q: Can this product be used in commercial products?

Yes. The WROVER module is certified for commercial use. This development board serves as a robust prototyping tool that helps businesses validate complex applications before integrating the bare WROVER module into custom PCB designs for mass production.

Q: Does this specific board have an external antenna connector?

Standard WROVER modules usually come with a PCB antenna. If the product title does not specify “WROVER-I” or “U.FL connector”, it uses the standard onboard antenna. Verify the physical product image if external antenna support is a requirement.
