For raspberry pi 3, broadcom have supported us with a new soc, bcm2837. The bcm2835 on the raspberry pi has 3 spi controllers. These connectors are backwards compatible with legacy raspberry pi boards, and support all of the available raspberry pi camera and display peripherals. Raspberry pi compute module cm1 raspberry pi compute. A raspberry pi ill use the pi 3 model b here, but any model with gpio pins will work if you want to use the pi zero youll need to solder some headers onto it. Newer computers and game consoles have replaced the old machines where most of us learned to program. J8 pinout 40pin header the diagram below illustrates the gpio pinout using the pi4jwiringpi gpio numbering scheme. It also includes the serial pins and the i2c pins, including printable pdf diagrams for classroom use. The raspberry pi gpio pins used for aux spi spi1 are. This article documents the pinouts for the first version, and the second version called revision 2. The comprehensive gpio pinout guide for the raspberry pi. This gpio pinout is designed to be both a quick and interactive reference to the raspberry pi gpio pins, plus a comprehensive guide to your raspberry pi s gpio interfaces. The cm3 contains a bcm2837 processor as used on the raspberry pi 3, 1gbyte lpddr2 ram and 4gbytes emmc flash. It means that if you plug the raspberry pi 3 into your hdtv, you could watch.
Thus a peripheral advertised in the manual at bus address 0x7ennnnnn is. In order to keep the system complexity low and data throughput high, the bcm2835 axi system does not always return read data inorder 2. The pi4b has 1x raspberry pi 2lane mipi csi camera and 1x raspberry pi 2lane mipi dsi display connector. Chapter 10 in the bcm2835 arm peripherals datasheet describes this controller. The pi4j project pin numbering raspberry pi 3 model b. 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. Rpi framebuffer documentation on bcm2835s frame buffer and mailbox. Only the spi0 controller is available on the header. The gpu has special logic to cope with data arriving out. C library for broadcom bcm 2835 as used in raspberry pi. On rpi 2, the peripheral addresses are different and the bcm2835 library gets. The raspberry pi 3 model b board contains a single 40pin expansion header labeled as j8 providing access to 28 gpio pins. The general purpose input output gpio pinout is almost the same for rev 1 and rev 2 versions of the raspberry pi due to them having the same bcm2835 processor. The purpose of this datasheet is to provide documentation for these.
