Changes
#1 Changed resistor (R39) from not fitted to fitted.
Type: BOM Change
Reason: Do not allow floating signal "OTG_ID".
Impact: None.
#2 Changed DCDC EN6347QI (U1) to MPM3860GQW-Z and adapted power circuit.
Type: Schematic Change
Reason: EOL of Component.
Impact: None. Increased output current capability. Minor changes in electrical characteristics.
#3 Changed DCDC EN5311QI (U3) to MPM3834CGPA-Z and adapted power circuit.
Type: Schematic Change
Reason: EOL of Component.
Impact: None. Increased output current capability. Minor changes in electrical characteristics.
#4 Changed load switch TPS27081ADDCR (Q1) to MP5077GG-Z and adapted circuit.
Type: Schematic Change
Reason: BOM Optimization.
Impact: None. Increased current output capability. Minor changes in electrical characteristics.
#5 Changed SD Card connector (J4) from 504077-1891 to 104031-0811.
Type: Schematic Change
Reason: EOL of Component.
Impact: Mechanical component size increased.
#6 Changed ETH PHY (U6) power supply to use internal LDOs.
Type: Schematic Change
Reason: Follow Marvell recommendation.
Impact: None.
#7 Added ESD protection diode (D1, D2) for USB.
Type: Schematic Change
Reason: ESD Protection.
Impact: None. Added ESD protection.
