Descriptions
1
SCL_CC3000
(1)
Output
I2C clock signal output from the CC3000 module. This
pin is connected to SCL_EEPROM through a 0-
Ω
resistor and is not used by end users.
2
SCL_EEPROM
(1)
Input
I2C clock signal input from EEPROM inside the CC3000
module. This pin is connected to SCL_CC3000 using a
0-
Ω
resistor and is not used by end users.
3
SDA_CC3000
(1)
Input/Output
I2C data signal from the CC3000 module. This pin is
connected to SDA_EEPROM using a 0-
Ω
resister and is
not used by end users.
4
SDA_EEPROM
(1)
Input/Output
I2C data signal from EEPROM inside the CC3000
module. This pin is connected to the SDA_CC3000
device using a 0-
Ω
resistor and is not used by end users.

VIO_HOST
Power In
VIO power supply from the host to the module. For the
MSP430 host platform, VIO_HOST = VBAT_IN. For other
platforms that have different voltage levels from battery
voltages, R14 can be removed.
9
VBAT_IN
Power In
Battery voltage input to module. For the MSP430 host
platform, VIO_HOST = VBAT_IN. For other platforms
that have different voltage levels from the battery
voltages, R14 can be removed.
