Streaming audio + video over 3g to vps using mk, which configuration to choose?

Question

Raspberry Pi

Hello, the task was to stream from the camera and microphone to vps via 3g, we decided to use Raspberry Pi, but as it turned out, this MK does not have a built-in audio card, you need to use either a usb card or a special one to connect a microphone. module, but the size of this device is very important to us. it is planned to carry it in a bag, and when using an audio card + 4g modem, it becomes somehow big and clumsy. Is there any better solution? Thank you.

Answer 1

I will answer myself: Raspberry Pi zero + board - usb hub for it + 4g modem + external audio card + powerbank
