Recommendations for carrier board design

Theboardhas168pinsplacedallaroundthemodule.Therearetherefore42pinsforeachside.
Paddimensionsare0.4x1.5mmwithapitchof0.8mm.Therearealso4GNDconnectionsatthemodule
cornerswhicharenotincludedinpincount.

WerecommendtousethefollowinglandingpatternforsolderingthemoduleonthecarrierboardPCB.




Wesuggesttoavoidrunningnoisytraces(e.g.highspeeddigital,RF,highcurrenttraces,etc…)underneath
themoduleonalayerwherethemoduleismounted.Signaltracescanberunonathirdlayerunderthesolid

PCB planarity

WerecommendtotrytoachievethebestplanarityinPCBmanufacturingandfinishingprocesstoimprove
themechanicalstrengthofsolderjoints.
Wesuggesttousehorizontalfinishingprocesses(e.g.ChemicalGold)andtocontactyourPCBmanufacturer
inordertoachievethebestcompromisebetweenplanarityandothercharacteristics(e.g.neededpadstack,

GPIO Driven during Boot Program Execution
TheAtmelbootloaderpresentontheCPUoftheDevelBoardusesseveralGPIOsinperipheralmodeto
communicatewithexternalmemorydevices.CaremustbetakenwhentheseGPIOsareusedbythe
application.Theconnecteddevicescouldbeunintentionallydrivenatboottime,andthuselectricalconflicts
betweenoutputpinsusedbythebootloaderandtheconnecteddevicescouldoccur.Toassurethecorrect
functionality,itisrecommendedtoplugincriticaldevicestootherpins,notusedbybootloader.The
followingcontainsalistofpinsthataredrivenduringthebootprogramexecution.Thesepinsaredriven
