Part identifier Jumper type Description Reference section
• 2-3 shorted: VDD_IO_ABC supply is
produced from MCU_VDD_REG supply
JP9 1x3 pin header VDD_ANA supply power source selection
jumper:
• 1-2 shorted (default setting): VDD_ANA
supply is produced from VDD_REG supply
• 2-3 shorted: VDD_ANA supply is produced
from MCU_VDD_REG supply
JP10 2x3 pin header V_SEC supply power source selection jumper:
• 1-2 shorted: V_SEC supply is produced from
P1V8_EXT supply
• 3-4 shorted: V_SEC supply is produced from
jumper JP37 output
• 5-6 shorted (default setting): V_SEC supply is
produced from 1V8_DCDC supply
JP11 (DNP) 1x2 pin header VDD_PA_2G4 supply enable jumper. JP11 is
not populated on the board. If populated, it can
be used to enable VDD_PA_2G4 supply for +10
dBm RF output.
JP12 1x2 pin header VDD_LDO_CORE supply enable jumper:
• Open: VDD_LDO_CORE supply is OFF
• Shorted (default setting): VDD_LDO_CORE
supply is ON
JP14 1x2 pin header VDD_RF supply enable jumper:
• Open: VDD_RF supply is OFF
• Shorted (default setting): VDD_RF supply is
ON
JP15 1x2 pin header VDD_CORE supply enable jumper:
• Open (default setting): VDD_CORE supply is
OFF
• Shorted: VDD_CORE supply is ON
JP35 1x2 pin header MCU_VDD_REG supply enable jumper:
• Open: MCU_VDD_REG supply is OFF. This
jumper setting also enables onboard current
measurement using MCU-Link.
• Shorted (default setting): MCU_VDD_REG
supply is ON
JP37 1x3 pin header Jumper JP10 pin 4 power source selection
jumper:
• 1-2 shorted (default setting): Jumper JP10 pin
4 input power is produced from VDD_REG
supply
• 2-3 shorted: Jumper JP10 pin 4 input power is
produced from MCU_VDD_REG supply
JP41 1x2 pin header VBOARD supply enable jumper:
• Open: VBOARD supply is OFF
• Shorted (default setting): VBOARD supply is
ON
