Hi Guys,

It's possible to mount all these devices I have mentioned in the topic without issues?? I'm trying to develop a time tracker attendance device.

Do you think that can be done?? Also I want to understand how to check the ports used by any shield I choose.

In what way do you mean mounted? You could create your own PCB with all of the appropriate hardware on, yes.

In terms of checking which port, what do you mean? You think that maybe one or more of your prototype shields for example may both be trying to access a serial port at the same time?
