Test Point Descriptions
(1)
Test points are not designed to carry current. They are intended for measuring voltage.
(2)
The test points for high current nodes (BAT, AC, USB, DCDC1, DCDC2, and DCDC3) are designed to
measure voltage at their respective input/output capacitor.

Jumper Descriptions
Table 3. Jumpers
Jumper
Description
JP6
Connects battery to battery voltage sense input. User should only install this jumper if use of the battery charger is
desired and the supply connected to BAT is capable of sinking current.
JP9
Used to pull PWREN either high or low. If not installed, the software can control PWR_EN via the GPIO_PWR_EN
signal.
JP11
Connects TS input to a 10k resistor to simulate a thermistor. If using a battery pack, do not install this jumper. Instead,
use J4 to connect thermistor to TS.
JP18
Connects VIO to 3P3. Do not install if other VIO supply is desired.
JP39
Allows user to select input to LS1
JP42
Allows user to select input to LS2
ISINK1
Connects LED string to ISINK1. Must connect to use LEDs.
ISINK2
Connects LED string to ISINK2. Must connect to use LEDs.
