Raspberry Pi 4 hardware configurations options
I’ve just learned about a really cool command for Raspbian OS, available in recent (Debian 9.0 based and later) Raspbian OS releases: pinout command shows you a visual presentation of what hardware configuration your Raspberry Pi has.
Simply type pinout, you don’t even need to use sudo. You’ll see output consisting of 3 parts that are so visual that I’ll screenshot two of them to show you exactly what to expect.
First part of the otuput looks really cool – it shows you the model name and the system board layout – where power and HDMI connections, where Ethernet port is and where to plug in USB (mind you, this is not Raspberry Pi 4 but Pi 2 instead):

Then you get the second part of the output, which is additional hardware info about your Raspberry Pi:
Finally, the last part of the output of the pinout command is actually the pinouts layout for the GPIO part of Raspberry Pi plaform:
