It also provides information about flashlights, sensors, vibrator, buttons, status indication LEDs and test

points to help customers use the Smart EVB G2.

Power Supply Interfaces (J0201/J0202)

4.1.

The Smart EVB G2 can be powered by an external 5.0V DC power adapter. Connect the DC power

adapter to the power jack (J0201) and then the step-down converter (DC-to-DC converter), which is used

to regulate the 5.0V DC power supply voltage to 4.2V for powering up the module.

The Smart EVB G2 can also be powered by a Li-polymer battery through the battery connector J0202 on

the board.

The following figure shows the simplified power supply block diagram of Smart EVB G2.
