Reference source not found. .
Designator Module supply Source
3V3 VBAT Can be connected to 3V3_DCDC or 3V3_EXT
VIO VIO Can be connected to 1V8_VIO or VIO_EXT
1V8 1V8 Can be connected to 1V8_DCDC or 1V8_EXT
Table 6: Input voltage options
Table 7 describes the different options to select the module input voltages using jumper J1-J7.
Jumper settings Remarks/Voltage levels
VIO (3.3 V) VIO (1.8 V)
Selects the power supply from the host interface (SDIO or
USB) or common external supply (VEXT) and on-
board DC-DC generated voltages.
VIO is derived from either 1V8 or 3V3.
• VBAT – 3.3 V
• 1V8 – 1.8 V
• VIO – 1.8 V or 3.3 V
Selects the power supply using separate external input
sources for each of the voltage rails VBAT, 1V8 and VIO.
External supplies are connected to J101-J103 at the
bottom of the EVB carrier board.
