Descriptions
Core module for performance evaluation (for more information, see the CC3000
module data sheet).
Can be used for radiated testing by reworking the capacitor to correct pads
U.FL RF connector used for conductive RF test
Used to switch between test mode and operation mode. When pins 2 and 3 are
shorted, J2 runs in operation mode. When pins 1 and 2 are shorted, J2 runs in test
mode.
Used to test power consumption. The pins of the jumper are shorted in operation
mode. For power testing, the jumper is removed and an ammeter bridges the pins.
Through-hole test points (For more information, see Table 2-3.)

Mode
Description
Test mode: CC3000 radio tool⁽¹⁾
Connect pins 1 and 2. Test mode is used with the CC3000 radio tool for operating,
testing, and calibrating the CC3000 chip-set 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.
