We have sourced a quality Micro USB cable that we supply with all sensors and dongles. However if you want to purchase some more to leave in other towers then you can.
Our cables provide both power and data. This is important as if you use a 3rd party cable it may just supply power which means it will charge the sensors but it will not allow you to connect the dongle to your computer.
We have designed the hole entry for the sensors and dongle around this cable – others may well fit but please be careful when trying alternative cables as they all tend to have a variety of sizes of plastic surrounding the actual plug.
