(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.

6 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.
