Key Parts Descriptions

CC3000MOD Core module for performance evaluation (for more information, see the CC3000

module data sheet).

Antenna Can be used for radiated testing by reworking the capacitor to correct pads

J1 U.FL RF connector used for conductive RF test

J2 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.

J3 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.

J4 Through-hole test points (For more information, see Table 2-3.)

J5 Through-hole test points (For more information, see Table 2-4.)

Table 2-2. J2 Configuration of the CC3000 EM Board

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.
