Power Supply

Two power supply sources are available on the HL Series Development Kit:

DC jack (via CN402)

LABO connector (via CN401/CN400)
Figure 9. Power Supply Connector (CN402, CN401 and CN400)
Either power supplies can be used to supply the development kit, or they can be used to supply power
to VBAT_BB and VBAT_RF separately depending on CN403 and CN404's jumper configuration.
Refer to the following diagram for possible configuration settings.
Figure 10. Power Source Selection (Schematic Diagram and Actual Development Kit Picture)
Other interfaces on the development kit are powered by VBAT, which is connected to VBAT_BB
through CN405 (refer to Figure 21 Jumper for Supplying the Development Kit Interfaces Separately
for the location of CN405).
