Table 2-2 describes the J2 configuration of the CC3000 EVM board.
Table 2-2. J2 Configuration of the CC3000 EVM Board
Mode Description
Test mode: CC3000 radio Connect pins 1 and 2. Test mode is used with the CC3000 radio tool to operate, test, and
tool
(1)
calibrate the CC3000 chipset designs during development. This tool uses the RS232/UART pins
to run radio frequency (RF) RX and TX tests on the CC3000 module. For more information, see
the
CC3000 wiki .
Functional mode: Normal mode Connect pins 2 and 3. Normal mode is for regular functionality between the host platform and the
CC3000 module.

C 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.
3 SCL__EEPROM Input I
2
C 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.
4 SDA_CC3000 Input and output I
2
C data signal from the CC3000 module. This pin is
connected to SDA_EEPROM using a 0- Ω resistor and is
not used by end users.
5 SDA_EEPROM Input and output I
2
C data signal from EEPROM inside the CC3000
module. This pin is connected to SDA_CC3000 using a
0-
Ω resistor and is not used by end users.
