If you have to pay a visit to a remote site from time to time, you may have to take a laptop with you to do some changes of the configuration of the RFzero. But you may also use your phone or a tablet to connect to the RFzero. If your phone or tablet has a USB-C connector you will have to use a USB data Type C to Type A adapter also. The current rating should be at least 500 mA and make sure the adapter does have data transfer. Some are charging only!

Example of a USB-C – USB-A data and current adapter.
