ESP32 Development Boards

ESP32 processors are available on hundreds of development boards produced by Espressif Systems and third-party manufacturers. Although many boards appear similar, they may use different ESP32 processors, memory configurations, USB interfaces, GPIO layouts, and peripheral hardware.

Understanding the relationship between the processor, module, and development board can help ensure the correct board is selected for a particular project.

Board Names Can Be Misleading

Development board names are not standardized. The same board name may be used by multiple manufacturers, while different boards may use the same ESP32 processor. Always verify the processor family (Original ESP32, ESP32-S3, ESP32-C3, etc.) before purchasing or selecting firmware.

Figure 1 – Common ESP32 development board styles.

Processor vs. Module vs. Development Board

Many beginners use these terms interchangeably, but they refer to different parts of the system.

Component Description
Processor The ESP32 integrated circuit (Original ESP32, ESP32-S2, ESP32-S3, ESP32-C3, ESP32-C6, etc.).
Module A certified RF module containing the ESP32 processor, flash memory, crystal, antenna, and supporting circuitry that can be soldered onto a development board or custom PCB.
Development Board A printed circuit board that adds USB programming, voltage regulation, reset circuitry, pushbuttons, and GPIO headers.

Development Boards by Processor Family

The ESP32 family includes several processor generations. Each generation is available on numerous development boards with different capabilities and intended applications.

The following table provides a general overview of commonly encountered development boards. Additional information about each processor family is provided below.

ESP32 DevKit V1 Original ESP32 USB, GPIO headers Most common general-purpose development board.
NodeMCU-32S Original ESP32 USB, GPIO headers Widely available and inexpensive.
DOIT ESP32 DevKit Original ESP32 USB, many GPIO Common clone with many GPIO available.
LOLIN32 Original ESP32 Compact design Compact board produced by WeMos/LOLIN.

ESP32-C6 Development Boards ESP32-C6 Wi-Fi 6, IEEE 802.15.4 Newest family with expanded wireless capabilities.

Processor Families

Original ESP32

The original ESP32 remains the most widely used processor family for DIY holiday lighting. It provides dual-core processing, Wi-Fi, Bluetooth, generous GPIO resources, and broad firmware support. Most existing ESP32-based lighting controllers use this processor family.

ESP32-S2

The ESP32-S2 adds native USB support and additional security features but removes Bluetooth capability. Although less common in holiday lighting, it is available on several development boards and may be useful for USB-connected applications.

ESP32-S3

The ESP32-S3 expands upon the original ESP32 by adding improved processing performance, native USB support, additional GPIO options, and vector instructions for AI and signal processing. It is becoming increasingly common on newer development boards.

ESP32-C3

The ESP32-C3 is based on the RISC-V architecture and is intended for lower-cost and lower-power applications. It offers fewer GPIO resources than the original ESP32 but remains suitable for many single-controller lighting applications.

ESP32-C6

The ESP32-C6 is the newest member of the ESP32 family and adds Wi-Fi 6 and IEEE 802.15.4 wireless support while continuing Espressif's transition to the RISC-V architecture. Support in holiday lighting firmware continues to evolve as additional hardware becomes available.

Board Features

Development boards commonly include:

  • USB programming interface
  • 3.3-volt regulator
  • Reset button
  • Boot button
  • GPIO headers
  • Status LED
  • Power LED

Some boards may also include:

  • Ethernet
  • OLED display
  • Battery charger
  • LiPo connector
  • MicroSD socket
  • Camera connector
  • CAN interface

Choosing a Development Board

When selecting a board, consider:

  • Processor family
  • Number of GPIO pins
  • USB connector type
  • Board size
  • Ethernet support
  • Available flash memory
  • PSRAM (if required)
  • Firmware compatibility
  • Community support and available documentation

For most holiday lighting projects, an inexpensive general-purpose development board is usually sufficient.

Firmware support varies between projects. While many development boards can run firmware such as WLED, ESPixelStick, ESPHome, or Arduino applications, the specific boards supported by each project may differ.

For a current list of hardware supported by ESPixelStick, see Supported ESPixelStick Platforms.

Development Board Recommendations

Application Suggested Board
General WLED Controller ESP32 DevKit V1
ESPixelStick ESP32 DevKit V1 (Original ESP32)
Compact Controller ESP32-C3 Development Board
Native USB ESP32-S3 Development Board
Ethernet Controller WT32-ETH01

Notes

Not every development board exposes every GPIO pin available on the ESP32 processor. USB interfaces, Ethernet hardware, voltage regulators, LEDs, and other onboard circuitry may reserve or limit the use of certain GPIO pins.

Always consult the board documentation and firmware compatibility information before assigning GPIO pins to holiday lighting functions.

Clones

Many ESP32 development boards are produced by multiple manufacturers. Boards sold under different brand names may be electrically identical while using different PCB colors, USB chips, or component layouts.

Most clone boards function normally, but users should verify GPIO assignments, USB drivers, and voltage regulator quality before use.
