#Notes: -Unit costs based on minimum orders of 25 components.
        -Headers are bought as large pieces and seperated,
         hence the fraction after each breakable header
        -populate R4 to enable OTG for AT90USB???7, but then do not use pin PE3
	-operation at 3.3V requires 8MHz crystal - ABM7-8.000MHZ-D2Y-T
	-if populating SRAM and running at 5V use 16MHz crystal - ABM7-16.000MHZ-D2Y-T
	-if populating SRAM (IC4,IC5), regulator ST1L05B (IC2) and associated
         components (R11,R12,C22,C26,D1) are uneccessary as SRAM requires 5V operation
	-CR1,CR2,R13,R14 can be populated instead of USB Switch (IC3,R10,R16) if
         using the AT90USB???6 as these ICs do not have host capability
	-Vcc_Sel (K1) is only required if using the regulator (IC2).  Can just short
         center and 5V pin to force 5V operation when using SRAM IC (IC4,IC5)
	-MBR120VLSF can be replaced with MBRX120LF in SOD123-compatible package
	-74AHC573 can be replaced with 74VHC573 in TSSOP20 package
