Raspberry Pi Gpio Header Extension
Raspberry pi 40 pin gpio layout.
Raspberry pi gpio header extension. A 40 pin gpio header is found on all current raspberry pi boards unpopulated on pi zero and pi zero w. Any of the gpio pins can be designated in software as an input or output pin and used for a wide range of purposes. The raspbery pi 26 pin 2 x 13 female header is designed to be soldered onto a pcb. These pins are to communicate with other circuitry such as extension boards custom circuits and much more.
In this raspberry pi gpio tutorial we are going to take a look at all the basics of the gpio pins or also known as the general purpose input and output pins. If you are reading the raspberry pi copyright statement printed on the pcb then pin 1 is in the bottom left and pin 40 is in the top right. The extensionblock is an add on board for the raspberry pi and it is a three way gpio extension board for the 2 20 pin header. Gold plated 26 pin double row 2x13 socket connector extension fo.
The majority of raspberry pi models use the same 40 pin header. Raspberry pi has a total of 26 pins on the edge of board used for talking to other devices. Each header sits approximately 8 5mm above the pcb once installed. The models that use this configuration are.
General purpose input output or gpio extension board for raspberry pi is the bridge between the infinite possibilities of what could be entered and what we can get from raspberry pi. At its corners the board provides holes for spacers locking posts or other tightening setups. It can then used to plug in a 26 pin gpio device such as a raspberry pi or breakout board.
