HardwareOverview
TheSi4703BreakoutBoardbreaksoutmultiplepinsfromtheIC.Forthepowerbus,the3.3VandGNDpinsarebrokenout.KeepinmindthatwhiletheICistolerantup
to5V,thecommunicationpinsareonly3.3Vtolerant,andthereforeshouldonlybeusedin3.3Vsystems.Ifyouneedtousethisina5Vsystem,checkoutourtutorialon
