    I'm considering streamlining my MySensor nodes by replacing the Arduino Mini Pro's by just ATmega328 DIP chips. Since I'm using nRF24l01 modules which already have an oscillator on it, I was wondering whether I can just branch it of at the soldering points and additionally connect it to the clock pins of the 328 MCU? (Thereby saving 2 capacitors and a crystal)

    Thanks in advance for any info!

      no You can't, but You do not need an oscillator for atmega if You do not need precise timings, just use atmegas internal oscillator.

        Thanks!
        Will consider using the internal one...
