R28 Connects the voltage source from
PWR1 to Board_VCC
Disconnects the Board_VCC from
PWR1 connector
R29
R29 Connects the voltage source from
PWR2 to Board_VCC
Disconnects the Board_VCC from
PWR2 connector
R28
R115 Connects the net Unregulated_VCC
(JA6-23) to Board_VCC.
(R30 and R31 Must be removed if
supplying unregulated VCC)
Disconnects Unregulated_VCC
from Board_VCC
R30, R31
R30 Connects the net CON_5V (JA1-1) to
Board_VCC. External 5V supply can
be connected at CON_5V.
(R28, R29, R115 and R31 Must be
removed if supplying 5V from
CON_5V)
Disconnects CON_5V from
Board_VCC
R115, R31
R31 Connects the net CON_3V3 (JA1-3) to
Board_VCC. External 3.3V supply can
be connected at CON_3V3.
(R28, R29, R115 and R30 Must be
removed if supplying 3.3V from
CON_3V3)
Disconnects CON_3V3 from
Board_VCC
R115, R30
R32 Supply power to the Microcontroller
VCC pin
Disconnects power supply to the
microcontroller VCC pins. Supply
current to the MCU can be measured
across ‘J5’
