UCTRONICS 20cm40pin Breadboard Jumper Wires Male to Female Ribbon GPIO Cable for Connection Raspberry Pi 3 2 Model B B+ w/3.5/5 inch Touch TFT Screen LCD display

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.

I bought this to separate the temperature sense hat from my raspberry pie. The Pi was giving off heat that made the readings too high. This fixed it. Wish it came in solid colors. If you're hear for the same reason I am. Then it works and the cable is quality. Fits Raspberry Pi

While the female end fit on the Pi perfectly, the male end was oversized for the connector so you have to be a bit careful aligning the pins to ensure they’re connected correctly to whatever you’re plugging into your GPIO.

Used it to distance my digital audio hat away from a PI 4 for radiation and heat issues.

This GPIO ribbon works as you would expect. I will say is durable, as I had to modify it to work with my raspberry pi touchscreen by cutting the plastic shroud to fit. The plastic put up a decent fight. Everything fit as intended and the pins were stiff, as they should be.
