UCTRONICS Male to Female GPIO Ribbon Cable 40pin 8inch Breadboard Jumper Wires for Connection Raspberry Pi 5 3 2 Model B B+ w/ 3.5/5 inch TFT Touch Screen LCD Display

It's standard size length gets the job done but I would of loved if it had been a bit longer. Still great product I would buy again

Good quality and is as described. I bought for doing self learning.

Cut it in half and use them to jump from a rPi daughter board to a mother board for a complete system.

I like the extra connector on the ribbon cable. This allows me to connect a LCD to the ribbon cable since it was already terminated in a block. The circuit board's printing is easy to read despite it being narrower than another extension that I have. The breadboard's holes seem a little loose but so far haven't caused a problem. Pushing the extension board's pins into the breadboard caused some of the metal bands on the bottom to push out. Pushing them back in was easy enough. The jumper wires appear to be well constructed and so far the pins on each end have not separated from the wire. One caveat I found with the extension board is that if you install it where the printing on the board matches the direction of the printing on the breadboard the positive and ground rails on the sides of the breadboard are reversed.

This review is for UCTRONICS Male to Female GPIO Ribbon Cable 40pin. There isn't a lot to say about this cable, and that is actually a good thing. Everything was done right on the cable that I received. It has the correct pin connections on both connectors to extend a Raspberry Pi GPIO hat outside the case. The strain relief on the cables is decent and the plastic connectors are good. Really, there is no reason to have a color coded cable, but it does let you verify that the cable is wired correctly. It is kind of nice to look at instead of another dull grey ribbon cable. I'm using this cable with a GPIO breakout board HAT that has LEDs, so it was very easy to tell that the cable was wired correctly. The length is enough to get outside the case without a lot of extra to flop around or introduce noise on the signals. I won't put the top on my case, but this cable will fit nicely through a small slot that is open on at least one side. The connectors obviously won't fit through a slot the size of the ribbon cable unless it is at a seam between the top and bottom.

Haven't tried any others to compare to but I needed a breadboard, a ribbon cable for my pi, and a way to plug the ribbon cable into the breadboard, so this was exactly what I needed and it is working great. The jumper cables are male-male, you might also want to get some male-female ones if you want to go from the breadboard to another PCB with male pins on it.

I've been using the UCTRONICS GPIO Breakout Kits for an annual virtual marketing event for years now. These are anywhere from 36 to 50 people over zoom. The UCTRONICS ones have been my favorite since they have large and clear lettering plus they also get the +/- to the rails on the breadboards. But several times they've arrived with 2 different kinds of breadboards. If you want to keep the colors aligned on the voltage, the numbers might go right to left or go left to right. When that happens, we have to scurry and order other breadboards to swap them out. When you've got that many people learning remotely, everything has to be consistent, especially when you are trying to guide or debug. This last time I left a poor review because I was unhappy with this inconsistency. They reached out offering to fix the issue and asked for some details on my orders. It took me a few days to get all of the order numbers to them to validate I'd purchased as many as I said I had. (Some were ordered by the marketing firm and shipped to me for quality check and assembly.) I was going to go in and raise the review and add some more positives, but see they seem to have somehow gotten my initial review pulled. That to me is a bad sign. When a vendor gets reviews pulled then we can't trust them or the system. So here is the review again. I purchased multiples of these, and they are not consistent. It won't impact everyone, but it sure impacts my usage.

Great GPIO t-cobble board kit. I love the power pins for both 3v and 5v that supply voltage to the power rails on the breadboard without needing jumper wires. The color ribbon cable is nice, and the quality of the breadboard good
