Raspberry Pi B V1 2 Pinout
The raspberry pi 2 model b board contains a single 40 pin expansion header labeled as j8 providing access to 28 gpio pins.
Raspberry pi b v1 2 pinout. This gpio pinout is an interactive reference to the raspberry pi gpio pins and a guide to the raspberry pi s gpio interfaces. This offers and increase of 14 pins over the 26 pin header on the original raspberry pi. Pi hardware raspberry pi 1 model b model b io pins note that we are not currently sure if the new pin 27 40 pwm1 gpclk1 and gpclk2 peripheral pin functions will be made accessible under raspbian and if so which pins they will be assigned to hence the duplicated pins shown with these functions. Gpio pinout rasp pi 1 model b rasp pi 2 model b.
So now i have 2 pi 3 s from china 1 from the uk 1 b 1 pi zero 1 2 1 pi zero w and my first is a model b rev 2 with 512 mb ram. This ic is pam2306aypke which is utilised in battery powered portable applications allowing the batteries to last longer. A 40 pin gpio header is found on all current raspberry pi boards unpopulated on pi zero and pi zero w. Raspberry pi pinout diagram circuit notes how to navigate your raspeberry pi 3 model b if you build it they will program.
Reply tony hansen on march 17 2018 11 39 pm. The raspberry pi gpio pinout guide. Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header. The raspberry pi b v1 2 uses a step down dc dc converter integrated circuit ic u3 with the markings c2 cg uoz.
The raspberry pi compute module 3 cm3 is a range of ddr2 sodimm mechanically compatible system on modules soms containing processor memory emmc flash on non lite variants and supporting power circuitry. Gpio pinout rasp pi 1 rev1 and rev2. The genesis of the raspberry pi came from a few college students concerned about the dwindling number and skills of students applying to study computer science. Pins 1 2 39 40 are also labeled below j8 pinout 40 pin header.
One of the most significant changes to the raspberry pi model b is the 40 pin header j8. And faster interfaces is a strong competitor for the raspberry pi. Newer computers and game consoles have replaced the old machines where most of us learned to program. Pinout also includes dozens of pinouts for raspberry pi add on boards hats and phats.
