Looking for Complete reference application / schematic of STWBC86 Wireless transmitters

[crm04140]

Hi I plan on using STWBC86 for a wireless charger prototype. I was looking at the datasheet for the reference designs and found that the reference schematics has missing or has hard to read values, labels, and wires. Is there a better version of the schematics that is clear and completed? 

If there is not, can anyone give recommendations for the highlighted parts?

I have also attached the original Schematic as a PDF below so you can see the clean version as well.

vin_sense/tp2 is for test
3.It is GND
4.miss GND
5.this is usb shell
6.This P2 need connecter, connect FT I2C and TX I2C pins
7.this is FT gnd

Fantastic!

Thank you for the quick and detailed answer. They were very helpful and was much more clear. 

I still have some followup questions:

3) There still is a node without any wires connecting to it. Is this just an graphical error?

6) I found the missing connections on the new schematic link. However, I don't understand what you mean by "connect FT I2C and TX I2C pins". I don't see these pins in the "USB-I2C convertor diagrams.

9) Thank you for letting me know that it is a test point. But how are they connected to VSSA, VSSD, VSSP if one end is ground and the other end is a test point?

Hi

3.Yes,it is error, thank for point it
6.P2 connector one side is wlc i2c pins, one side is ft260 i2c pins
7.there are all gnd, VSSA is analog gnd, VSSD is digital gnd, VSSP is power gnd.
