I have a task and I did some research on it. It is a first design for me where I am using 32 bit microcontoller. The task is to develop a small PCB module (schematic and design) with a microcontroller STM32 and a 4G SIM module SIM7070G with a SIM card holder.The board should be powered from a 100-240VAC 50/60Hz input. 2 interfaces are required in each board:1- 4p 2.54mm for programming the microcontroller with STlink.2- 4p 2.54mm for reading debug and output messages from microcontroller.Is there anyone who can help me finding some reference designs to design point number 1 and 2 above? Thanks in advance.

have you managed to find any evaluation boards?I would suggest looking at "SWD" for 1 and "UART" for 2, should be on pretty much every ST Evaluation board.

Thanks a lot @ATHONOR I have checked the evaluation board and found the schematics there. It was very helpful

You're welcome, the hardest part is knowing where to look sometimes!
