The MPR420 design was developed and certified for use in the Japanesse
market.  The full schematics are not in the public domain, but we can help
you if you have specific requirements.

Please contact Crossbow directly at info at xbow.com

Thank you,
Mike Horton

Subject: [Tinyos-help] MPR 420(mica2)  mote building prob

hi Im currently building a mote based on the berkeley mpr420(mica2). Now

xbow has all the schematics for each individual part but not a full 
schematic connecting all parts together. Can you help? what connects the

amtel chip to the radio chip?

thanks
