Arduino + Serial + PCB

[yu_buffon]

Hi there, I have been working on a little project where my Arduino Uno sends the IMU sensor's data to the PC via serial (Printing the data on serial monitor. I ma planning the transfer the programmed Arduino chip (Atmega) from the prototype platform to a PCB. I have read that I just need a crystal and a couple of capacitor to run the already programmed Arduino chip on a PCB. And I could use the prototype platform to program the chip and transfer back o the PCB. My question here, can the Arduino on the PCB still perform the serial communication with the PC? Does the PCB need extra components in order to perform the serial communication? Please explain.

Not really understand your question, sorry.

how do u connect the arduino to PC now? through the USB connector on arduino board?
if yes, then u will need extra thing to convert the uart signal to the usb of PC.
