Raspberry Pi GPIO Pin Reference

Raspberry Pi GPIO Pin Reference 6Microsoft Azure IoT Suite can be used to build extremely scalable Internet of Things (IoT) solutions. With any IoT solution the cloud platform is only half of what needs to be built. The other half resides on physical IoT hardware devices such as a Raspberry Pi that are connected to some combination of sensors and / or actuators to provide the real-world integration side of the IoT solution. Both the Raspberry Pi 2 & 3 offer a 40 pin GPIO header to allow for many different components to be connected, in addition for the capability of providing both 3.3 volt and 5 volt output to those components. Each component needs to be connected to the correct pins, so a proper reference diagram is always necessary to ensure correct pin locations.

Raspberry Pi GPIO Pinout Reference

The Raspberry Pi 2 & 3 have a 40 pin header that supports UART, I2C, SPI, PCM, and has numerous GPIO pins. It additionally has pins for 5V and 3.3V power along with numerous Ground pins. When connecting sensors and other components it’s very important to connect to the right pins. For this reason it’s important to keep a good Raspberry Pi GPIO Header Reference diagram readily available for easy lookup.

Here’s a really simple diagram with the location and purpose of each pinout labeled along with the color coding for easier reference at a glance.

Locating Header Pin 1

In case you’re unsure where what the orientation of the above Raspberry Pi GPIO Pin Reference, all you need to do is locate the “J8” marking on the board and match it up with the “J8” in the reference diagram (as shown by the red arrow in the below image.)

Raspberry Pi GPIO Pin Reference 8

The location of Pin 1 and the “J8” marking on the Raspberry Pi board is in the corner of the board next to the header pins opposite of the Ethernet and USB ports. Pin 1 is the pin closest to the “J8” marking towards the inside of the board; not the corner pin on the outside edge of the board.

Microsoft IoT Grove Kit for Raspberry Pi

MSIoTGroveKitBoxThe IoT hardware landscape is ever changing from the new Raspberry Pi 3 to various Arduino boards. One thing Raspberry Pi has offered that Arduino hasn’t been capable of is to run Windows IoT Core. Now, the add-on device market for Raspberry Pi with Windows IoT Core has remained somewhat limited, as Windows IoT Core is still fairly new. This has meant wiring up servos, sensors and other things has been difficult for the average developer. With the introduction of the new Microsoft IoT Grove Kit you can now easily plugin servos, sensors, etc. with a single plug that really stream lines the prototyping process! Read More
