Hi,
For 7000 series GPRS/EDGE module, did you mean SIM7000E ?
I see from it's page it consume only a few micro amps.
Consumption
• Power off: 7uA
• PSM: 9uA
• Sleep: 1mA
• Idle: 11mA
and from their websites, it's shows that they have good documentation, design guide, application note, Hardware design Guide, and even evaluation board(this one I found on avnet page). We can explore it together to match it with your requirement.
My Background is Electronic engineering and I have Bachelor on it. Currently I work on defense & military Electronics Industry, so I always update with newest electronics trend.
Some of my recent freelancer project are related to IoT, On board PCB antenna, GSM module, etc.
This kind of board need more attention on PCB design especially on on board antenna and grounding. And I know how to deal with it.
Sim7000E come with a good documentation that we can explore to meet your requirement. I will help you to find the best approach for this project need.
Lets discuss it over messenger.
Best Regards,
Rijal
