MainprocessorisadualcoreCortexM7runningatupto480MHzandaCortexM4runningatupto240MHz.The
twocorescommunicatewitheachotherviaahardwareassistedmailboxonwhichArduinoimplementsa
RemoteProcedureCallmechanismthatallowscallingfunctionsontheotherprocessorseamlessly.
Bothprocessorscansharealltheperipheralsandresourcesandbothcanrunthefollowingapplications:
