MiFi External connections

Okay yes please let me know about power. Basically we are hoping to use MiFi as the logic controller for a cellular based IoT project. The system needs to be powered by 12V, so we have a 12V -> 5V regulator board but it’s far more convinient/better to be able to directly wire from header pins between the regulator board and MiFi then to have to get Micro-USB pigtails just to supply power!

EDIT: Just noticed that in the picture on the MiFi page one of the images shows the circuit board for version 2.2. On that version of PCB there is a 2 hole position J19 that is marked V_5V and Gnd, which looks like exactly what I would need. Can you confirm this?

 

Is the included cell antenna built into the MiFi plastic case then, or? Because we will be using the GPIO headers to integrate with other components I had thought to remove the case and just use the main Mifi circuit board (we are already putting all components into a larger plastic enclosure anyway), but if the antenna is part of the case may have to change that plan. Is there also an antenna for Wifi, or is that built onto the PCB? (I think the domino core board that powers MiFi has a uFL connector too no?)
