UCTRONICS Male to Female GPIO Ribbon Cable 40pin 8inch Breadboard Jumper Wires
Bottom line: The UCTRONICS Male to Female GPIO Ribbon Cable 40pin 8inch Breadboard ($7.99 on Amazon as of 2026-10-21 16:27 UTC): 40 peel-apart wires let you split off only the leads your project needs; main trade-off: separate leads have no keying, so a wire can land on the wrong GPIO pin.

Pros & Cons
Pros
- ✓ 40 peel-apart wires let you split off only the leads your project needs
- ✓ About 20 cm / 8 in long, enough to reach a breadboard or display beside the Pi
- ✓ Male-to-female ends bridge Pi GPIO header pins and breadboard holes
- ✓ Rainbow color coding makes each GPIO connection easier to trace
- ✓ Soft copper wire bends around cases and tight project layouts
Cons
- ✗ Separate leads have no keying, so a wire can land on the wrong GPIO pin
- ✗ 8 in length may fall short for displays mounted far from the board
- ✗ No pin labels on the wires; you need a separate GPIO pinout reference
- ✗ Listing gives no wire gauge or current rating for higher-power loads
Manufacturer description
The UCTRONICS 40-pin Male to Female GPIO Ribbon Cable gives you 40 color-coded jumper wires joined in a single rainbow flat ribbon. Each wire is about 20 cm (8 inches) long. Plug the female ends onto your Raspberry Pi's 40-pin GPIO header and run the male ends to a breadboard, a 3.5 or 5 inch TFT touch screen, or a sensor module. That keeps the wiring off the board itself. The wires peel apart, so you don't have to use all 40 at once. Split off only the leads your project needs, such as four for an I2C sensor, a handful for a display, or one for an LED. Separated groups also reach…
SpecPicks Verdict
SpecPicks scored UCTRONICS Male to Female GPIO Ribbon Cable 40pin 8inch Breadboard… using a rating × review-volume × price-fit model applied to published specs and reviews across the cables & connectors category. UCTRONICS's cables & connectors lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for cables & connectors of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions
Does this cable work with the Raspberry Pi 5?
Yes. UCTRONICS lists the Raspberry Pi 5, Pi 3, and Pi 2 Model B and Model B+ as compatible. The female ends plug onto the board's 40-pin GPIO header pins.
How long are the jumper wires?
Each wire is about 20 cm (8 inches) long. That's enough to reach a breadboard or a small TFT display placed next to the Pi.
Can I pull the wires apart and use just a few of them?
Yes. The 40 wires are joined in a flat ribbon that can be separated into groups of any size. You can use only the leads you need and reach non-standard, odd-spaced headers.
Can I use it to connect a 3.5 or 5 inch TFT touch screen to my Pi?
Yes, that is the use UCTRONICS designed it for. The cable links a Raspberry Pi board to 3.5 or 5 inch TFT LCD touch displays. Check your display's pinout to confirm which GPIO pins it needs.
What comes in the package, and is there a warranty?
The package contains one 40-pin, 20 cm male to female breadboard jumper ribbon cable. The listing doesn't state warranty terms, so check the product listing or contact UCTRONICS for current coverage.
