EC200A Mini PCIe pinout (datasheet)

IoT Modules LTE Standard Module

I am using EC200A with Mini PCIe and want it to implement gsm calls, as I know basic EC200A supports analog audio and has pins for speaker and microphone. I want to know if my version does have the same pins in my package also I can’t find a pinout for my version with PCIe on the internet only EC200T and I am pretty sure that It should be slightly different. if anyone has a solution, please.

P.S. I know that it has a digital audio interface PCM but I want to avoid designing codec in the circuit

Hello, I have an ec200a connected to a minipcie slot on an acer motherboard. I’m running Linux. ttyUSB* devices are correctly created and I can access modem with minicom but I don’t know how to access audio to implement call. Do I need to write a custom module or should alsa recognize PCM output on minipcie slot by itself?

Thank you.
