atmega328 tqfp pcb design
-
I would like to design in eagle atmega328 tqfp pcb. what is the bare minimum for board component (much like the microsensor board published here but only the arduino mcu functioning). I would like it to run on the chip internal clock.
so what would I need to get in the BOM just for minimal arduino functioning? (caps and resistorts if any) -
It would be advisable to have decoupling capacitors (100nF) on all supply pins, ISP header for programming, maybe a serial FTDI header for serial (incl. 100nF cap between DTR and reset pin on atmega), 10K pullup on reset line.
In theory you can drop all the components, and only have the atmega (and ISP header for programming).
