Descriptions
+ and - are terminals for connecting an external load
to the DA9070 VDD_SYS; S+ and S- are kelvin
sense points for DA9070 Buck input. For input
voltage measurement during efficiency test, S+ and
S- should connect to multi-meter for better accuracy.
Install J2 jumper will connect the VBAT pin of
DA9070 to battery positive terminal VBAT_P through
current sense shunt resistor. It also enables battery
current monitoring using external current probe.
+ and - are terminals for connecting external power
supply to the Boost input; S+ and S- are kelvin sense
points for the Boost input. For input voltage
measurement during efficiency test, S+ and S- should
connect to multi-meter for better accuracy.
Install J6 jumper will connect the IMON pin of
DA9070 to STM32L151(U8) ADC input. It also
enables IMON current measurement using external
multi-meter. Position 2-3 should be used.
Install J9 jumper will connect LDO_0 input
(VDD_LDO0) to VDD_SYS_M of DA9070.
Install J10 jumper will connect LDO_1 input
