Hi,
I have developed SIM7000 based module before. Most of my recent projects were related to IoT, wether it's Cellular, WiFi, or BLE based battery powered device. I'm familiar with certain issues related to Cellular module like SIM7000. I know how to choose proper power supply module for it, chose battery management IC, how to route antenna circuit properly, and standard working circuit for SIM7000 module.
Appart from that, I have 8 years experience on PCB design. I have built lot of projects for various application. From hobbyst, Industrial, IoT, and even for military.
Let's discuss the details over chat. Let's finish this project.
Best Regards,
Rijal
