How to check the hardware version

For Linux/ Raspberry of course

By AP, 

            
Here are some handy commands that can be used to check the hardware version on a Linux-based machine.


uname -a: This command displays detailed information about the kernel version, which can be helpful for identifying the hardware. Example:


tom@rpi0-yo3iti:~ $ uname -a
Linux rpi0-yo3iti 6.12.25+rpt-rpi-v6 #1 Raspbian 1:6.12.25-1+rpt1 (2025-04-30) armv6l GNU/Linux


cat /proc/cpuinfo: This command shows detailed CPU information, including a hardware revision code.


tom@rpi0-yo3iti:~ $ cat /proc/cpuinfo
processor	: 0
model name	: ARMv6-compatible processor rev 7 (v6l)
BogoMIPS	: 996.14
Features	: half thumb fastmult vfp edsp java tls
CPU implementer	: 0x41
CPU architecture: 7
CPU variant	: 0x0
CPU part	: 0xb76
CPU revision	: 7
/
Hardware	: BCM2835
Revision	: 9000c1
Serial		: 0000000000005b6d
Model		: Raspberry Pi Zero W Rev 1.1



cat /proc/cpuinfo | grep Revision: This command isolates the revision code from the cpuinfo output:


tom@rpi0-yo3iti:~ $ cat /proc/cpuinfo | grep Revision
Revision	: 9000c1



pinout: Running pinout in the terminal provides a visual map of the GPIO pins and includes information about the specific hardware model.

Add action button in WordPress code editor toolbar
By AP,  
Most of my website posts that include code use syntaxhighlighter to nicely format code. Unfortunately, you have to manually tag the piece of text as code. I thought it would be nice to have one or more buttons in the classical editor toolbar that will automatically surround the code with needed tags to be displayed […]


                            

                                
                                                                    
                            

                        

                    

                

                        

                    

                        

                            
Changing Quartus Prime project folder
By AP,  
I want to get back to FPGA design because I have some projects in mind and I did some in the past that were quite fun and very interesting. I am a bit rusty, though, and I am afraid I have to review all my past, and very diluted, experience with FPGAs. This has a […]

I recently ran into an issue with my Raspberry-based radio node. I tried to connect to some othet WiFi access points and I realized that I had no idea how to set connection priorities if I have multiple candidates for connection. I was used with wpa-supplicant way of doing things which was just to add […]

More work today. Some wires got loose and I did some experiments with .asoundrc and ALSA settings. I added a 39 Ω ballast resistor on SDIN and SDOUT lines and put a ferrite core on both wires. The radio node works as expected, absolutely no issues with one exception, a periodic pop that is audible […]

While testing my I2S project I ran into some boot issues on the Raspberry Pi 4 host. For what seemed to be some unknown reasons the boot process was completely chaotic, sometimes running well, sometimes hanging. I banged my head for some time looking for a solution until it came to my mind to change […]

Today I managed to connect the Digilent Pmod I2S2 to a Raspberry Pi 4 and have all frequencies generated. This is part of an older project that I left abandoned for a while: a radio node built on Raspberry Pi and using Svxlink. As known, Raspberry boards do not have a proper audio interface and […]
