Raspberry Pi 3 B Gpio

The raspberry pi 3 model b is the final revision in the raspberry pi 3 range. This offers and increase of 14 pins over the 26 pin header on the original raspberry pi. The only change is a switch to which uart is exposed on the gpio s pins but that s handled internally by the operating system.

Raspberry pi 3 b gpio. A powerful feature of the raspberry pi is the row of gpio general purpose input output pins along the top edge of the board. Raspberry pi gpio layout model b one of the most significant changes to the raspberry pi model b is the 40 pin header j8. This means that you can t use the pwm output and play audio through the 3 5mm jack at the same time. Prior to the pi 1 model b 2014 boards comprised a shorter 26 pin header.

See below for the raspberry pi gpio pinout diagram. The earlier models such as the raspberry pi b have just 26 pins. Raspberry pi gpio plus reference pinout compatible with raspberry pi model a b zero 2 3 3b and 4 only 0 8mm thick idiot proof really. The pwm pin available on the gpio header is shared with the audio system true for model b so presumably true for model b not confirmed as full schematic not yet available.

Plug and play system that requires no drivers or set up. We ve whipped up a simple graphical raspberry pi gpio pinout. The raspberry pi 3 features the same 40 pin general purpose input output gpio header as all the pis going back to the model b and model a. With this you can add breakout boards add on boards or just about anything desined to connect on a raspberry pi b a gpi.

The above raspberry pi gpio triple expand baord allows you to convert a single gpio header on your raspberry pi into three. 4 usb 2 0 ports. 2 4ghz and 5ghz ieee 802 11 b g n ac wireless lan bluetooth 4 2 ble. Documentation usage gpio gpio.

A 40 pin gpio header is found on all current raspberry pi boards unpopulated on pi zero and pi zero w. Gigabit ethernet over usb 2 0 maximum throughput 300 mbps extended 40 pin gpio header. Broadcom bcm2837b0 cortex a53 armv8 64 bit soc 1 4ghz. You can t put it on backwards two pack of the raspberry pi gpio plus reference pinout card see more product details.

If you re an owner of a raspberry pi b 2 zero or 3 then you will have 40 pins in total. If you orient your pi such that you are looking at the top with the gpio on the right and hdmi port s on the left your orientation will match pinout. Pin 1 is the only pin with a square solder pad which may only be visible from the underside of your pi. We have included all three iterations of the pi for the pinout diagram.
