2.3 Connector and Jumper Descriptions
2.3.1 Push-buttons and LEDs
Table 1 lists the push-button descriptions.
Table 1. Push-buttons
Reference Usage Comments
SW3 Factory default
This button is used to restore the serial flash to the factory default image. Hold the
button and then toggle the RESET push-button.
SW2 RESET
This button can be used to reset the device. Holding the button down sets the device in
the SHUTDOWN state.
SW1 nHIB
This button boots the device to the bootloader mode for flashing the firmware over a
universal asynchronous receiver/transmitter (UART).
Table 2 lists the LED descriptions.
Table 2. LEDs
Reference Color Usage Comments
D3 Red PWR indication On, when the 3.3-V power is provided to the board.
D6 Yellow nRESET
This LED indicates the state of the nRESET pin. If this LED is glowing, the
device is functional.
D5 Green nHIB
This LED indicates the state of the nHIB pin. When the LED is off the device
is in HIBERNATE state.
D7 Red Factory default
This LED indicates whether the factory default switch is pressed on. The
RESET button must be pressed for this LED to function.
2.3.2 Jumper Settings
Table 3 lists the jumper settings.
Table 3. Jumper Settings
Reference Usage Comments
J6 USB connector
For powering the BoosterPack™ when connected with a LaunchPad™, which
cannot source enough current.
J7 Power selection
Choose the power supply from the LauchPad™ kit or the onboard USB.
J8 (1 to 2) power from the MCU LaunchPad™
J8 (2 to 3) power from the onboard USB using a 3.3-V LDO
J8 Current measurement
For hibernate and LPDS currents, connect an ammeter across J26
(range < 500 µA).
For active current, mount a 0.1- Ω resistor on R42, and measure the voltage
across the 0.1-
Ω
resistor using a voltmeter (range < 50 mV peak-peak).
P1…P4 BoosterPack™ header 2 × 10 pins each connected to the LaunchPad™
J10 RF test (2.4 Ghz only)
U.FL connector for conducted testing in the lab. Using this requires an ECO be
made to the board by swapping two resistors.
J11 RF test (2.4 GHz + 5 GHz)
U.FL connector for conducted testing in the lab. Using this requires an ECO be
made to the board by swapping two resistors.
