Header J2 and J3
J2 and J3 are a 6-pin headers used to select the voltage supply for banks 1B and 1C (J2) and
bank 2F (J3). By default, the jumpers connect pin 1 and 2, which is 3.3 V. Connect the
jumpers as shown in the following table to change the voltages..
Jumper
VCCIO1B_1C (J2)
VCCIO2F (J3)
Connect pins 1 and 2
3.3 V (default)
3.3 V (default)
Connect pins 3 and 4
2.5 V
2.5 V
Connect pins 5 and 6
1.8 V
1.8 V
Warning:
For J2 and J3, only select one voltage at a time; otherwise you may damage the board.
Header J4, J5, and J6 (Power Select)
J4, J5, and J6 are headers you use to select the voltage and/or power up sequence option. Use
a jumper across 2 pins to make your selection.
•
J4 controls the voltage (5.0, 3.3, and 2.8) for the 4 MIPI headers and 2 LVDS headers
•
J5 controls the voltage (3.3 and 1.8) for the 4 MIPI headers and 2 LVDS headers
•
J6 controls the voltage (1.2) for the four MIPI headers
