2.2 Jumper Settings
Table 2 ‐ 3 lists the jumper settings on the BOOSTXL ‐ CC3120MD
Reference Usage Comments
J7 USB connector For powering the BoosterPack when connected with a LaunchPad which cannot source enough
current.

J8 Power selection Choose the power supply from the LauchPad kit or the on-
board USB. J8 (1-2) power from MCU LaunchPad
J8 (2-3) power from on-board USB using 3.3 V LDO
J6 Current
measurement
For Hibernate and LPDS currents, connect an ammeter across J6 : Range (< 500 µA)
For Active current, mount a 0.1
Ω resistor on R35 and measure the voltage across the 0.1 Ω
resistor using a voltmeter (range (< 50 mV peak-peak)).

P3, P4 BoosterPack
header
2x10 pins each connected to the LaunchPad.
J3 LED EN. For Enabling/Disabling the LED’s.
J4 Reset Pullup For keeping the reset up
J2 RF Test U.FL connector for conducted testing in the lab. Using this requires an ECO to be made to the board
by swapping two resistors.

2.3 2x20 Pin connector assignment
Table 2 ‐ 4 lists the outer row connectors of the two 20 ‐ pin headers.
Note: All signals are 3.3V CMOS logic levels and are referred with respect to the CC3120 IC.
For example, UART1_TX is an output from the CC3120 IC.
For the SPI lines, the CC3120MOD always acts like a slave
