Hi,
i want to make a breakout board for the atmega328p with needed components to operate properly.
It is sort of an arduino, but with a different pinout,layout and use.
I need a pinout diagram of the chip( TQFP package) with the pins marked with the names on the arduino boards.
For example(probably not correct): Pin1 on the chip - pin D5 on the arduino
If you can send a picture, or even write the pinouts in the comments it will be very helpful.
Thanks.
So like a Pro Mini ?
Basically, yes. I want to make this board to learn how to implement the atmega328p in a project in the best way possible. I want to make more profesional boards in the future, and using the whole arduino with headers really is not practical for me.
which pins are the digital pins? i can only see the analog inputs marked
All the pins are digital pins, D0 to D19 on an Uno. Only A6 and A7 do not have digital functions, they are analog inputs only.
D14 to D19 have their signals routed internally to an analog multiplexer when then goes to the ADC. They are labelled on the board as A0 to A5.
In the diagram they are shown as 14/A0, 15/A1, 16/A2, ...19/A5, in the lower right hand corner.
