The ESP32 is a popular and powerful microcontroller that is used in a wide variety of applications, from IoT devices to robotics. However, with so many different ESP32 development boards available, it can be difficult to know which one you have.

This guide will help you identify the ESP32 chip and development board that you are using. We will cover the following topics:

• Identifying the ESP32 chip
• Identifying the ESP32 development board

By the end of this guide, you will be able to confidently identify the ESP32 chip and development board that you are using.

Identifying the ESP32 Chip

The ESP32 chip is a small, rectangular chip that is typically found on the bottom of an ESP32 development board. The chip is marked with a variety of information, including the chip’s model number, revision number, and manufacturer.

To identify the ESP32 chip, you can look for the following markings:

• Model number: The model number of the ESP32 chip is typically located in the top left corner of the chip. The model number is a four-digit number, such as “ESP32-WROOM-32.”
• Revision number: The revision number of the ESP32 chip is typically located in the bottom right corner of the chip. The revision number is a two-digit number, such as “1.0.”
• Manufacturer: The manufacturer of the ESP32 chip is typically located in the bottom left corner of the chip. The manufacturer is typically a company name, such as “Espressif Systems.”

Here is an example of an ESP32 chip:

Using the ESP32 Chip Identifier Tool

If you are unable to find the ESP32 chip markings, you can use the ESP32 chip identifier tool to identify the chip. The ESP32 chip identifier tool is a web-based tool that allows you to upload a picture of the ESP32 chip and identify the chip’s model number and revision number.

To use the ESP32 chip identifier tool, visit the following website:

Once you have visited the website, click on the “Upload Image” button and select a picture of the ESP32 chip. The tool will then identify the chip’s model number and revision number.

Using the ESP32 Chip Datasheet

If you are unable to find the ESP32 chip markings or use the ESP32 chip identifier tool, you can use the ESP32 chip datasheet to identify the chip. The ESP32 chip datasheet is a PDF document that contains detailed information about the ESP32 chip, including the chip’s model number and revision number.

To find the ESP32 chip datasheet, visit the following website:

[https://www.espressif.com/en/products/hardware/esp32/resources](https://www.espressif.com/en/products/hardware/esp32/resources)

Once you have visited the website, click on the “Datasheet” link and select the ESP32 chip datasheet for your chip’s model number. The datasheet will contain the chip’s model number and revision number.

Identifying the ESP32 Development Board

The ESP32 development board is the circuit board that contains the ESP32 chip. The development board also includes a variety of other components, such as a USB connector, a power supply, and a debugging header.

To identify the ESP32 development board, you can look for the following markings:

• Model number: The model number of the ESP32 development board is typically located on the top of the board. The model number is a combination of letters and numbers, such as “ESP32-DevKitC.”
• Revision number: The revision number of the ESP32 development board is typically located on the bottom of the board. The revision number is a two-digit number, such as “1.0.”
• Manufacturer: The manufacturer of the ESP32 development board is typically located on the back of the board. The manufacturer is typically a company name, such as “Espressif Systems.”

Here is an example of an ESP32 development board:

Author Profile

Carla Denker

Carla Denker first opened Plastica Store in June of 1996 in Silverlake, Los Angeles and closed in West Hollywood on December 1, 2017. PLASTICA was a boutique filled with unique items from around the world as well as products by local designers, all hand picked by Carla. Although some of the merchandise was literally plastic, we featured items made out of any number of different materials.

Prior to the engaging profile in west3rdstreet.com, the innovative trajectory of Carla Denker and PlasticaStore.com had already captured the attention of prominent publications, each one spotlighting the unique allure and creative vision of the boutique. The acclaim goes back to features in Daily Candy in 2013, TimeOut Los Angeles in 2012, and stretched globally with Allure Korea in 2011. Esteemed columns in LA Times in 2010 and thoughtful pieces in Sunset Magazine in 2009 highlighted the boutique’s distinctive character, while Domino Magazine in 2008 celebrated its design-forward ethos. This press recognition dates back to the earliest days of Plastica, with citations going back as far as 1997, each telling a part of the Plastica story.

After an illustrious run, Plastica transitioned from the tangible to the intangible. While our physical presence concluded in December 2017, our essence endures. Plastica Store has been reborn as a digital haven, continuing to serve a community of discerning thinkers and seekers. Our new mission transcends physical boundaries to embrace a world that is increasingly seeking knowledge and depth.
