Xiatiaosann USB 2.0 Type A open-wire cable set for Arduino-style DIY (5 male + 5 female, 4-pin)
Product description
The essentials
If you’re building, repairing, or just tinkering with USB-powered electronics, an open-wire USB lead like this can be genuinely handy. This Xiatiaosann set is based on USB 2.0 Type A female jack / male plug and breaks it out into a 4-pin style DIY connection, which is exactly the kind of thing you look for when you don’t want to rely on a pre-made board header cable.
On paper it covers both power and basic data wiring. The coloured conductors make it straightforward to match polarity and data lines: red is positive, black is negative, white is data negative, and green is data positive. That sort of clarity matters when you’re trying to get a DIY USB power supply or a simple wiring job right first time.
There’s also a practical limitation worth flagging: this is described as for DC 5V USB devices and the listing notes it cannot be adapted to fast charging plug adapters. So if your goal is high-speed or charging-aggressive setups, it may leave you wanting.
Key points for DIY use
What stands out here is the mix of DIY convenience and clear wire mapping. Instead of guessing which wire goes where, you can follow the stated colour scheme for power and data. That makes it easier to connect into development boards and small USB devices where you can access the needed pins.
The kit includes multiple pieces rather than a single cable: 5 USB male cables, 5 USB female cables, and 40 connectors. For hobbyists and makers, that’s useful if you’re likely to remake leads, tidy up wiring, or keep spares for future projects.
What matters most in the specs
The cable is specified as USB 2.0 Type A female jack / male plug, using 28AWG wire gauge. The wire length is given as 30cm (about 11.8 inches), and the rated power side is DC 5V with a rated current of 2A.
Tech specs
- Type: USB 2.0 Type A female jack / male plug

Why it’s worth it (and where it can fall short)
This set makes sense if you want a simple, DIY-friendly USB lead for low-voltage electronics and wiring practice. The listing also mentions oxygen-free pure copper wire core, with the idea of lower resistance and purer current flow, which is the kind of detail you usually care about when you’re running at or near the stated current.
Still, it’s not perfect for every situation. The description warns that using a power supply output current higher than 2A could pose a risk of overheating and fire. That doesn’t mean you’ll have problems every time, but it does mean you should treat the 2A rating as a real boundary and avoid pushing it beyond what it’s meant for.
Also, it’s framed as suitable for DC 5V USB devices (for example Arduino development boards, light bars, small fans, and mobile phones). If you mainly need fast charging or you’re expecting advanced USB data behaviour beyond basic transfer, you may find this cable is more “straightforward wiring tool” than “all-singing, all-dancing USB lead”.
Everyday use examples
Imagine you’re powering an Arduino development board from a USB port and you want to avoid a bulky adapter. With these wires, you can sort out red/black for power and green/white for data as stated, then use the included connectors to tidy the connections for a neat, repeatable setup.
Or say you’re replacing a damaged lead for a small USB-powered fan in a prototype enclosure. You’d cut back to a clean connection point, match the polarity using the red and black guidance, and keep the wiring tidy thanks to the pre-coloured conductors.
Buying verdict
It’s a good fit if you’re doing DIY electronics work, need a USB Type A to open-wire 4-pin style lead, and value having multiple cables plus connectors rather than one-off spares.
It may not be a great match if you’re specifically chasing fast charging or you want to adapt this into fast-charging plug setups, since the listing explicitly says it can’t be adapted to fast charging plug adapters. You should also consider skipping if your planned power draw tends to exceed the 2A rating—this cable is described with a safety warning tied to that limit.
For most hobby and prototyping use cases at DC 5V, it’s the kind of cable set that can save time. Just double-check the wire mapping (red/black for power, white/green for data) before you connect anything.
FAQs
What devices is this USB cable meant for?
The listing points to DC 5V USB devices such as Arduino development boards, light bars, small fans, and mobile phones.
Does it support data transfer?
Yes, it’s described as having both power and data transfer wiring, with specific data negative and data positive wires listed (white and green).
Can it be used for fast charging?
No—according to the description, it cannot be adapted to fast charging plug adapters.
How long are the wires?
The wire length is stated as 30cm (about 11.8 inches). If you need longer runs, you may want to plan for extension or different cable lengths.
Is the 2A rating important?
It can be. The description warns that connecting a power supply output current higher than 2A may create a risk of overheating and fire, so you should stay within the stated rating.
