GPIO Pinout Orientation RaspberyPi Zero W
I looked over various websites providing the pinout explanation, especially this . But I have trouble to figure them to the real rpi zero. I mean in the following image provides the pinout Information:
But I cannot figure out on real rpi if the
3v3pins are the ones located closer to sd card reader or not. In other words how I should place my RPi Zero against the image in order to figure out the pinout? Should the sdcard reader pointing towards left as I am looking it? (I use the sd card component as reference point in order to distinguish the pins more easily because rpizero has from one side the SD card reader and from the outher header the screen "slot")
Have you gone a Google on this? Like finding this? https://othermod.com/wp-content/uploads/Raspberry-Pi-Model-Zero-Mini-PC-500x405.jpg
For reasons of their own (saving space? fitting on an 80-column terminal? meeting the tradition of having pin 1 at top left?) the pinout.xyz folks have decided to represent the GPIO pins rotated 90° clockwise on their website and in the
pinoutcommand. The circles at top and bottom of their image are meant to represent the mounting holes.
If you have a Raspberry Pi without headers, pin 1 has a square pad while all the others are round. Also, there's a small diagonal corner cutout on the board silkscreen by pin 1.
