Product Description

The 38-Pin USB-C ESP32 is designed for engineers who need maximum I/O flexibility and modern connectivity. The USB Type-C port is more durable than traditional Micro-USB and allows for easier connection with current cables. With 4MB of Flash memory and 520KB of SRAM, this board can handle complex web servers, encryption, and data-intensive tasks. The 38-pin layout breaks out nearly every internal pin of the module, including multiple ADC channels, SPI, I2C, and capacitive touch sensors.

Key Features

  • Modern USB Type-C: Simplifies connectivity and provides a more robust physical connection for frequent programming cycles.

  • Premium CP2102 Serial IC: Offers superior driver compatibility and stability compared to CH340 variants, especially on macOS and Linux.

  • Maximum GPIO Breakout: Access to 38 pins allows for high-density sensor integration and complex peripheral control.

  • Dual-Core Architecture: Enables dedicated processing for WiFi/Bluetooth tasks on one core while your main application runs on the other.

  • Integrated Wireless Stack: Supports a full range of internet protocols and BLE mesh networking for versatile IoT applications.

Technical Details

  • Dimensions: ~55mm x 28mm.

  • Power Management: Onboard 3.3V LDO regulator.

  • Buttons: EN (Reset) and BOOT (Flash) buttons for manual control.

Prototyping and Engineering Tips from Robogears

  • Breadboard Layout: Note that the 38-pin footprint is wide. It will cover all holes on a single standard breadboard. For easy prototyping, use two breadboards side-by-side or use Male-to-Female Jumper Wires to bring the pins to an open workspace.

  • 3.3V Logic Warning: All I/O pins operate at 3.3V. Connecting 5V sensors directly can damage the ESP32 chip. Use a Logic Level Converter for safe 5V interfacing.

  • Powering via VIN: If you are using many sensors, the USB-C port might not provide enough current. You can power the board with a stable 5V-9V supply connected to the VIN pin (ensure the grounds are connected).

  • Auto-Program Circuit: Thanks to the CP2102 and onboard circuitry, this board usually enters "flash mode" automatically in the Arduino IDE. If it fails, hold the BOOT button briefly when the IDE shows "Connecting...".

Package Includes

  • 1 x ESP32-WROOM-32 38-Pin Development Board (USB Type-C & CP2102)

Disclaimer

Double-check the pin labeling on the underside of the PCB before wiring, as different manufacturers may have slight variations in ground and power pin locations on the 38-pin format.
