the battery is fully charged. The TS pin is meant for an external negative temperature coefficient (NTC)
thermistor. In this kit, it is connected to GND through a 10K resistor.
is the charge enable pin which is kept
low always to enable the charger circuit. EN2 and EN1 pins are used to set the maximum input current at input
pin. EN2 is set as logic 1 through the 10K pull-up resistor (R154) and EN1 is set to logic 0 through the 10K pull-
down resistor (R152), which sets the maximum input current to be adjusted by external resistor (R59) connected
to pin ILIM. Currently, ILIM is designed to let 850 mA of current (R59). The output VOUT is decoupled with a 10µF
and a 0.1µF capacitor. VOUT will be in the range VBUS to VBUS-0.237 V while powering from VBUS, and VBAT to
VBAT-0.0625V while powering from the battery.

The EN pin is an input used to turn off the on-board regulators. An on-board resistive pull-up ensures that
regulators are on by default and an external trigger from wing board can be used to turn off the on-board supply.
