RPi GPIO Breakout Expansion Board + Ribbon Cable + Assembled T Type | 2 Set GPIO Adapter FC40 40pin Flat Ribbon Cable for Raspberry Pi B+ Kit for Connection

worked as expected.

Does the job and one of the best deals I found for the money. Needed this for a weather project I built with a raspberry pi needed to pull the sensors away from the board itself to prevent false readings.

Just successfully used this to attach a DS-3231 real time clock to my RPI 400B. Just plugged the cable in the back and then the T breakout GPIO extension board. Used a male/female jumper wire set to connect to the clock. I connected 4 pins on the clock to to breakout pins 2 for 5 volts, pin 6 for ground, pin 3 for SDA, and pin 5 for SCL. It used 4 jumper wires. The clock itself was the 5 pin type (one pin was not used) I might shorten the ribbon cable for my application. This set is a good value for 2 pairs. Product arrived in good condition. The writing is small and you need a magnifier but that is typical of a tiny board. Next I build a small cover for it all.

This is perfect for prototyping when using an electronic breadboard with Raspberry Pi. The pins are clearly marked which helps prevent wiring mistakes.

I work with a rpi0w and sometimes is really hard to use the gpio with multiple cables and other things attach to it. I bought this cause the cable, I cut one end and peel some cables to manage and reroute in my project, I would love if they also Mark the ends with at least the basic pin 0 or something so it would be easy to identify the first times. It works perfect both cables

The traces on these boards have been through a lot - the soldermask is scraped away in many places, although I haven't come across an actually-disable trace yet. I was surprised to learn after trial and error that the IDC connector's keying (that ensures it fits into the PCB in the proper orientation) is not consistent - you must check by eye every time you plug one of these into a RasPi because it could be backwards with respect to another of the same product. IMPORTANTLY, what is labeled GPIO15 on the board is in fact GPIO16.

I used this for connecting my Raspberry Pi to a breadboard. As you can see from the first picture, it is really wide and only allows access to 1 row of pins on one side, and 2 rows on the other. Also, the other board that I have that is similar has the 5v and 3.3v power connected at the top of the rows (You can see it in the background of the 2nd picture). With a little work of adding the 5v and ground with jumpers and not needing 2 rows on the one side, it will work. I wish I had looked longer and found one similar to what I had. It came in a kit that I purchased.
