<p dir="ltr">I forgot to take picture on my tablet. I have four pins on one side and two on the other of the board. The side with two has printed on the main board "antenna" I suppose these are RF and ground. The trick is to figure the other four :)</p>
<p dir="ltr">I'm thinking of soldering it to my raspi or raspi zero if there usb header or pins are available.</p>
<p dir="ltr">So can safe usb port.</p>

Pretty interesting. A quick search on sparkfun ( <a href="http://sparkfun.com" target="_blank">http://sparkfun.com</a> ) turns up an Arduino shield using the RT5350, which looks to my untutored eye like a pretty similar part.

That means you are probably not going to be able to un-solder them from the carrier. Sounds like you have some poking around to do to figure out what is going on in there.

They could be extra power, extra ground, or even just there to strengthen the physical connection to the motherboard. <br><br>As a first step, I'd power on the tablet (assuming it's still un-broken enough to do that) and use a multimeter to try to figure out which connection(s) is//are vcc and which is//are ground.
