Hi
I have a GSM module and microcontroller, they are going to be connected using a USB on a PCB.
Previously, when I required much low data rates I used UART. And to monitor communications between the two devices I simpled used a simple tool such as USB- UART Convertor- CP2102 | Makerfabs Electronics
I would connect the TX pin from this tool to TX or RX pin on my microcontroller and I would be able to see the bytes being sent or received.
Can something similar be done for USB?
As USB is impedance controlled, I believe you can not simply add a pin header between trace from module to microcontroller to intercept it.
What is the correct way?
