General Purpose Input Output Extension board is the bridge between the infinite possibilities of what could be entered and what we can get from Raspberry Pi.
Not endless, though.
Raspberry Pi has a total of 26 pins on the edge of board used for talking to other devices.
Here are the pins.
You can use these pins to take data from sensor or to output data to LCD etc.
We have collected for you top best input output extension boards that you can use with your Pi.
10. Wangdd22 Raspberry Pi 2 / 3 Model B GPIO Extension Board ($15.99)
This is a high-quality universal GPIO extension board compatible with all the Pis with model B making working easier because of its multi-functional module. Also compatible with Orange Pi and Banana Pi.
9. Raspberry Pi 3,Pi 2,Pi Model B+ GPIO Expansion Extension Board by LOTW ($9.99)
This is also a universal GPIO extension board compatible with Raspberry Pi model B+ (1,2,3). One row of boards can change into 3 rows. Makes working easier and has a worthy design.

This consists of a 400 point breadboard and a 40 pin ribbon cable and a 40 pin T – cobbler. This board is compatible with Raspberry Pi Model B and B+. The pins are labeled for easy identification.
6. Makerfire® Raspberry Pi GPIO Extension Board ($7.99)
Labeling might be poor but a solid and easy board to use.
5. kwmobile GPIO Module V2.0 for Raspberry Pi B and B+ ($4.90)
This T – Cobbler can be directly plugged in with your Raspberry Pi using a cable (which doesn’t come with this). The pins are labeled for easy identification. This T – Cobbler can transfer data through its 40 pins. Compatible with Raspberry Pi 2 model B and Raspberry Pi B+.
4. T-Type GPIO Extension Board by LOTW ($11.99)
Compatible with Raspberry Pi B, B+. The GPIO extension adapter is of type T. The breadboard consists of 800 points. All GPIO pins work great and the kit is of good quality.
3. Raspberry Pi 2 and B+ GPIO Extension Board by Makefire ($8.89)
This model is compatible with Raspberry Pi 2 model B+. All the pins are labeled for easy identification. A great add-on that you can use with your Raspberry Pi to do numerous projects.
The pins solder might not be of good quality but you can unsolder them and then use the main 40 pins. It has a red LED which indicates that the power is ON and the board is working. The board is labeled loud and clear.
2. Kuman RPi GPIO Breakout Expansion Board ($9.90)
It consists of a 40 pin rainbow ribbon cable. The pins are labeled to assist in integration.
Everything works great. As expected. The expansion board and ribbon cable come sealed in a static – resistant packaging. The development board is labeled correctly. Highly recommended to anyone who wants to play about with the Raspberry Pi’s GPIO header feature.
“Fits breadboard perfectly. Allows easy and fast access to all GPIO pins. This item is a MUST for raspberry pi owners.”
1. Sintron GPIO Extension Board ($7.95)
This is specifically designed for Raspberry Pi model B+. With this kit you can connect your Raspberry Pi Model B+ 40 pin GPIOs direct to a breadboard.
The build is solid and you can work without the pain of thinking that wires might come loose. Clearly labeled and works great for debugging. Breakout board works without imperfections. It comes in a sealed package with foam pieces to protect the pins.
A great investment.
