adding Qi wireless charging to a CAT Phone (Problems with usb-c layout)

Recommended Posts

Posted · Original PosterOP



i am trying to add Qi wireless charging to my CAT S61 smartphone. So i bought a reciever on amazon (one of those nillkin qi tags) which connects per usb-c to your phone and you can stick that at your bach-cover.
but i want my phone to still be waterproof because thats the main reason i went for this CAT-Phone. I opened the phone already and put the tag under the back cover and it works BUT i have to solder the contacts of the tag to the contacts of my connector. And i am not sure which lanes i have to connect and where exactly they are. The Plan is that i can still charge through usb-c if needed and use it as a data connection to my PC.  
Can someone help me and tell me which lanes i have to add and where i have to solder them to?

I know that usb-c dont work like micro-usb because there is like a master-slave relationship going on and i dont know if i have to connect the data lanes and the cc lanes.

at the inside of the tag i can see that there are alot of lanes connected. i will send a photo of the disassembled tag if someone needs it.

here is the link to the tag:



thats the connector:



please excuse my english, i am from Austria

Thanks for you help =)

Here are the images from the tag. 

does anyone know if it will work when i only connect the V-Bus and the Ground lanes? or do i need to connect all lanes? and what if i connect another device to that port? Will it kill the board on the tag or not?(for example charging with a cable, Quick charge 3.0)
