White Board
7 Jumper settings
The following jumpers on the board are used for measuring the current consumption of
the corresponding power supply:
Reference Position Description
J6 1-2 Default Closed 12V power input after reverse protection diode
J7 1-2 Default Closed FS26 LDO1 (5V) output current
J89 1-2 Default Closed MCU VDD_HV_A current consumption
J8 1-2 Default Closed Buck 5V output current
J9 1-2 Default Closed FS26 LDO2 (3.3V) output current
J90 1-2 Default Closed MCU VDD_HV_B current consumption
J10 1-2 Default Closed Buck 3.V output current
J11 1-2 Default Closed 1.5V for MCU core
J12 1-2 Default Closed 1.2V for SJA1105 core
J34 1-2 Default Closed 12V power input for high side driver XS6500
J35 1-2 Default Closed 12V power input for LF driver NJJ29C2
J85 1-2 Default Closed 12V power input for FS5600
Table 7. Jumpers for current measurement
Other jumpers on the board are shown in below table:
Reference Position Description
J5
J87
1-2 Default Closed
1-2 Default Open
Enable SBC debug mode, thus watchdog refreshing from
SPI is not needed. J5 should be closed and J87 should be
open for FS26 entering debug mode.
J4 1-2 Default Closed Allow SBC FS0B to disable high/low side driver outputs.
Table 8. Jumpers for VBAT power supply source
The following figure shows the locations of these jumpers on the White Board.
