uBlox GPS control
#3
Final update

The chip is probably real but the block is probably a fake. I visited someone with a microscope and we took a closer look inside.

It looks like pin 9 simply connects to pin 11 via a choke. The place that I "think" VCC_RF comes from is a poorly formed pcb via which is bypassed to ground by the black component. It does not connect to anything else.

I believe that the green board is a knock-off Chinese copy of an original uBlox and the PCB design is flawed. You can see nearby some shonky track layouts and the fact that there is no other connection to pin 9 confirms my thinking.

In any case, the block simply doesn't look like a real uBlox item.
