How to Tell What Raspberry Pi I Have

Raspberry Pi boards are widely used for DIY projects, programming, and IoT devices. Over the years, multiple versions of the Raspberry Pi have been released, making it difficult to quickly identify which model you own. In this guide, we’ll explain how to tell what Raspberry Pi I have with various methods so you can determine your board accurately.

Why Is It Important to Identify Your Raspberry Pi?

Knowing your Raspberry Pi model can help you in the following ways:

• Ensuring compatibility with software and operating systems.
• Selecting appropriate power supplies and accessories.
• Avoiding hardware conflicts.
• Understanding processing power and limitations for your project.
• Facilitating technical support and troubleshooting.
• Making informed decisions for upgrades.

Let’s explore the ways to identify your Raspberry Pi model.

1. Inspect the Raspberry Pi Board

The first and simplest way to determine your model is by inspecting the physical board.

Find the Printed Model Name

1. Look near the GPIO pins or on the edge of the board.
2. Most boards display text like “Raspberry Pi 3 Model B+” or “Raspberry Pi 4 Model B.”

Compare Ports and Features

If the text is missing or unclear, use the ports and features to identify your model:

Model	USB Ports	HDMI Ports	RAM	Ethernet
Raspberry Pi Zero W	1 Micro-USB port	1 Mini-HDMI port	512MB	No
Raspberry Pi 3 B	4 USB 2.0 ports	1 HDMI port	1GB	Yes
Raspberry Pi 4 B	2 USB 3.0, 2 USB 2.0	2 Micro-HDMI ports	2GB, 4GB, 8GB	Yes
Raspberry Pi 400	3 USB 2.0 ports	1 Micro-HDMI port	4GB	Yes

Compare these details to narrow down your model.

2. Use Terminal Commands

If your Raspberry Pi is running, the easiest way to identify your board is through commands in the terminal.

Check /proc/cpuinfo

1. Open the terminal.
2. Type the following command:cat /proc/cpuinfo
3. Look for the line labeled “Revision.” This hexadecimal code indicates your Raspberry Pi model.

Use the official Raspberry Pi documentation to match the revision number with your board.

Run the pinout Command

Another simple command is:

pinout

This tool shows the GPIO layout along with the Raspberry Pi model name, making it easy to confirm how to tell what Raspberry Pi I have.

3. Identify Using Serial Numbers

Each Raspberry Pi comes with a unique serial number embedded in the CPU.

1. Open the terminal.
2. Enter:cat /proc/cpuinfo
3. Locate the Serial field.

While the serial number doesn’t directly tell you the model, you can use online tools or community forums to decode it and identify the board.

4. Check the Original Packaging

If you still have the box or manual that came with your Raspberry Pi, identifying the model is straightforward. Look for:

• The model name (e.g., Raspberry Pi 3 Model B+).
• RAM size and processor details.
• Labels like “Zero W” or “Compute Module.”

5. Compare Specifications Online

If you are unsure even after inspecting the board, compare its specifications with official Raspberry Pi documentation.

Key Features to Check:

• USB ports and their type (USB 2.0 or 3.0).
• HDMI ports (single HDMI, dual Micro-HDMI, or Mini-HDMI).
• RAM capacity (512MB, 1GB, 2GB, 4GB, or 8GB).
• Ethernet availability.
• Wireless connectivity like Wi-Fi and Bluetooth.

Cross-referencing these features will help you figure out how to tell what Raspberry Pi I have accurately.

6. Identify Through the Operating System

Your Raspberry Pi’s operating system can also hint at the hardware version.

Run the uname Command

1. Open the terminal.
2. Enter:uname -a

This displays the system architecture (e.g., ARMv6, ARMv7, or ARMv8), which correlates to specific Raspberry Pi generations.

OS Compatibility

Certain Raspberry Pi models perform better with specific OS versions. For example:

• Raspberry Pi 1 and Zero: Optimized for older Raspberry Pi OS versions.
• Raspberry Pi 4: Runs best with 64-bit Raspberry Pi OS.

Analyzing the OS performance can give you clues about your board’s model.

Conclusion

Identifying your Raspberry Pi model is essential for successful projects, troubleshooting, and upgrades. To summarize, here’s how to tell what Raspberry Pi I have:

1. Look for printed model details on the board.
2. Compare ports and physical features.
3. Use terminal commands like cat /proc/cpuinfo and pinout.
4. Check the serial number for identification clues.
5. Refer to original packaging or manuals.
6. Cross-reference board specifications online.

With these steps, you can confidently determine your Raspberry Pi model and ensure compatibility for all your projects. Whether you’re a beginner or an advanced user, understanding your Raspberry Pi will make your projects smoother and more efficient.
