Wiring Diagram for my future LTE plane

Coreman

Hello Everyone!

Last days I look to make my LTE plane, but for beginners like me, it is not simple.
After watching some YT videos and read some threads here, I made a wiring diagram with parts that should arrive soon.

In short, I will need a small help from experienced members.

So, can someone answer me, is this diagram correct?

I didn't find something similar here in the forum so maybe this thread can help also someone like me.

Kind Regards,
Marko

Coreman Hi and welcome.
Your diagram is correct. Thank you for sharing.
Couple of things i want to point out.

I would recommend that you use HiLink modem, e.g (E3372-H) instead of E220 (Stick type).

Make sure your total USB current consumption is not above the design criterias. For Pi3 B+ 1,2 A
If you go above the 1.2A, you would need a extra power supply connected directly to the USB port.

Hey Sinamics,
Thank you for your answer!
Ok, my UBEC output is 5v 3A, so I will use a resistor to decrease it to 1.2 A.
For now, I will use Huawei E220, because of the budget.
Later I will buy Huawei with HiLink performances.

Thank you for your help! 🙂
