    This adapter is great. No driver issues, no big bulky and expensive laptop. I have thrown this in my radio box so I never fly without it. On my quads when I use this USB adapter It dosen't power up the vtx so I can change the channel and power level without stomping on anybody's channel even if I am sharing a channel. I love this thing

    This is a very valuable, and must-have accessory for your Betaflight powered quad. No need to lug a laptop around, just your phone, or tablet. Plug the adapter into your FC, connect your phone or tablet via bluetooth, and away you go. This is a full fledged mobile Betaflight configurator adapter, at a very reasonable price. You need this!
