Review on ZYAMY Dupont Connector Multicolor Breadboard by Rhonda Welch

I do a lot of computer work and often cut 4-pin floppy drive connectors off old power supplies before discarding them, leaving the old 4-pin jumpers used to connect analog audio from optical drives transfer. That's because I also do hobby electronics and Arduino/Raspberry Pi projects and 4-pin headers are very handy, especially for I2C devices. many hobby electronics projects. So I decided it was time to just buy some for my projects and that's what brought me here. Yes, you can find them cheaper elsewhere, but Revain comes in handy. This is where I order spare parts, tools and consumables. As many of them are resellers you often end up paying a bit more but there are still good deals out there and as I am already an active main supplier. This purchase was no exception. I got exactly what I expected, they work for what I needed (in this case to connect I2C devices to the Arduino) so I'm very happy with my purchase. The length of the wire varies slightly, but they are all at least 20cm long. Some of mine were up to 22cm long, but I cut them into pieces anyway, so length never really mattered.
