Power Input Connectors
Connector J1 or J2 supplies input voltage to the VL-EPH-V6. Voltage is applied through one
connector only, not both. The VL-EPH-V6 accepts power input of 5V ± 5% or
+3.3V ± 5%. Jumper block V1 selects the input voltage (see Jumpers on page 10).
CAUTION:
A +5V input voltage must not be applied to the VL-EPH-V6 when 3.3V mode is selected.
Doing so will damage the board.
Connector J1 is a 2-pin header for use with a plug-in latching connector. This connector is
useful for lower current LVDS panels (in the 1-3 A range).
Connector J2 is a 2-pin screw terminal, useful for higher current panels (in the 3-4 A range).
Table 2 lists the pinout of the J1and J2 connectors and shows the location of pin 1 for both
connectors.
