Identify a Raspberry Pi Board

The most accurate way to identify which edition and model of a Raspberry Pi product is by using one of the following solutions. The rest listed are here as alternative methods that can be helpful depending on the circumstances.

  • Read the circuit board
  • Query directly via the console or terminal

Read Circuit Board

The majority of boards produced now have the edition and model printed directly on the top of the circuit board. See the illustration example below showing the location on the circuit board.

Note

The copyright year will not reflect the circuit board edition and model.

Read Circuit Board Processor

The Broadcom mark (BCM) is identifiable by the first few characters or a Raspberry Pi logo printed on top of the processor. Refer to the illustration example below showing the location on the circuit board.

Processor labels for each Raspberry Pi product.

Board Edition/Model Processor Label
1 2835
2 2836 / 2837
3 2837
4 / 400 2711
5 2712
Pico Raspberry Pi logo
Zero 2 W RP3A0-AU
Zero / W / WH B4432BBPA-10-F

Note

Raspberry Pi 400 is differentiated by the keyboard chassis.

Console or Terminal

Within the the console or terminal, choose one of the following methods.

$ cat /sys/firmware/devicetree/base/model

Raspberry Pi 2 Model B Rev 1.1


$ cat /proc/cpuinfo | grep Model

Model       : Raspberry Pi 2 Model B Rev 1.1

Tip

Use the tab key to help autocomplete the directory path.

Count Circuit Board Ports

You can generally determine which board it is by the Ethernet or HDMI ports.

Board Edition/Model Port
A Models No Ethernet
B Models Ethernet
1 - 3 HDMI
4 / 400 2 x HDMI micro
5 2 x HDMI micro
Pico No HDMI
Zero HDMI mini

Note

Raspberry Pi 400 is differentiated by the keyboard chassis.

Counting the amount of USB ports can be a pretty accurate identifier.

Board Edition/Model USB Ports
1 Model A 1
1 Model A+ 1
1 Model B 2
1 Model B+ 4
2 Model B 4
3 Model A+ 1
3 Model B 4
3 Model B+ 4
4 Model B 4, +1 USB-C for power supply
400 3, 1 USB-C for power supply
5 4, +1 USB-C for power supply
Pico 1 (micro USB)
Zero 1 (micro USB)

Note

Raspberry Pi 5 is differentiated by the on/off button.
