Hello everyone. I have a module for SIM5360E but it is not mounted on any board. I want to establish a connection between my module and my PC so that I can practice AT commands (there is no other option). I thought of using an external USB-to-Serial converter like CP2102 but it does not work. I looked up the pins of this module, would it be fine to just design a USB-to-Serial converter on the module itself and use that? I have no idea.
"It does not work" gives us not the tinyest information.

It seems you want to use UART interface:
then:
* voltage levels need to meet
* timing / baud rate needs to meet
* protocol / sent data needs to meet.
That´s it.
Voltage and timing is given in the datasheets. Every designer needs to read them. Nothing special.
Protocol is what data you send/receive with your PC.

Yes, you are correct. Voltage needs are approx. 3.4-4.4V, baud rate according to the datasheet is 115200 bps but I have seen in forums it can work between 9600-115200 so I have been trying all of them out, and the protocol/sent data is indeed met. I think the problem may be with the voltage so I am going to try to do some precise work with a voltage supplier today.
this is not what I meant. I did not mean to "try" .. I did mean to "know".
you gave one voltage range ... (and I don`t think this given range is correct)
but you need to match 8 ranges:
standardized RS–232 interface is used for the communication, and default values for the interface settings as following:
115200bps, 8 bit data, no parity, 1 bit stop, no data stream control

The logic interface is 0<>1.8V but Vbat is 3.4><4.4
Unfortunately, I do not have a board. Just the module itself. I was given the task of figuring out how to connect the module to the PC when I didn't have any board to go off of. Thank you for your resources and kindness, I will keep your knowledge in mind

Ah! Thank you kindly, I did not realise about half of these parameters. The voltage range I gave was for VBAT, though for the logic interface I'd need 0-1.8V. Sorry for the inconvenience, I am very new to this.
