This board is engineered for versatility, offering dual-core processing, ultra-low power consumption, and integrated Wi-Fi and Bluetooth capabilities, making it ideal for immediate prototyping in both individual and business environments.
Description
The ESP32 DevKitC is a small-sized ESP32-based development board produced by Espressif, designed to give developers easy access to the chip’s GPIO pins. It integrates the ESP-WROOM-32D module, which contains the high-performance Xtensa® 32-bit LX6 dual-core microprocessor capable of operating at up to 240 MHz.
This board provides comprehensive connectivity options with integrated 2.4 GHz dual-mode Wi-Fi (802.11b/g/n) and Bluetooth (v4.2 BR/EDR and BLE). These features allow for a vast range of applications, from connecting simple sensors to the cloud to building complex mesh networks or interfacing with mobile devices.
For programming and debugging, the DevKitC utilizes the widely recognized CP2102 USB-to-UART bridge, ensuring a stable and consistent connection with your PC via a standard Micro-USB cable. The board’s pin layout is designed to be highly breadboard-friendly, facilitating rapid prototyping by keeping standard 0.1-inch (2.54 mm) pin spacing while maximizing usable I/O access.
Manufactured with 40nm ultra-low-power technology, the ESP32 chip incorporates advanced power management features, including a deep sleep mode drawing less than 5 µA, which is critical for extending battery life in portable and IoT applications. It supports various development environments, including the official Espressif IDF, the popular Arduino IDE, and MicroPython, catering to diverse programming preferences.

Getting Started Guide (Arduino IDE)
  1. Driver Installation: Ensure the VCP drivers for the CP210x chip are installed on your computer.
  2. IDE Setup: In the Arduino IDE preferences, add the official ESP32 board package URL: raw.githubusercontent.com.
  3. Board Installation: Use the Boards Manager (under Tools > Board) to search for and install the “esp32 by Espressif Systems” package.
  4. Programming: Select “ESP32 Dev Module” or “ESP32 DevKitC” board from the Tools menu, choose the correct USB port, and upload your sketch.
Q: What is the difference between the "WROOM-32" and "WROOM-32D" modules?

The WROOM-32D is a slightly newer revision of the original WROOM-32 module, offering minor improvements in component layout or stability. They are functionally interchangeable for almost all development purposes.

Q: Is the CP2102 chip better than others like the CH9102?

The CP2102 is very common and well-supported, often automatically detected by major operating systems. The CH9102 is a reliable, lower-cost alternative. Both chips perform the same function effectively; the choice often comes down to driver preference.

Q: Can I power the board externally?

Yes. The board has a 5V pin which can accept an external regulated power supply (5V-12V range is often fine, check the specific board’s regulator limits), or you can supply regulated 3.3V directly to the 3.3V pin. Warning: Only one power source should be used at a time.

Q: Does this board support secure boot and flash encryption for commercial use?

Yes, the core ESP32 chip has hardware security features that can be configured using the Espressif IDF to protect intellectual property and secure communications in commercial products.
