Im trying to create a pcb for a project, and to utilise the Mega328p AU (SMD version) to which I can't find too many useful schematics online for my requirements.
I have a few clone nanos which I would take the parts from and re apply to my pcb.
I would like to talk to the Microcontroller via a USB port (Mini or micro depending on which is suitable) as I have micro and mini smd usb ports but most nanos come with a mini usb and I was wondering what's stopping me from using a micro USB port.
This will go to a CH340C chip, which as far as I can tell allows the mega329p to talk to the computer via a USB port, as the online Arduino pdf used an FT232RL and I can't seem to compare their wiring. I have some SMD HC-49S 16MHz crystals which are required and ceramic capacitors.
I would also like to use the reset button which is on all boards and the Leds, but I won't need the external headers.
Can anyone help me by pointing me in the right direction for each requirement or offer any help of their own?
Sorry for such a tedious post but any help is appreciated - Harvey
