Input Power Selection Switch S400

Battery ID and Thermistor Configuration DIP Switch S401
Battery ID and thermistor configuration is handled by the DIP switch S401. This switch has two sub
switches, one is used for battery ID and another one is used for battery thermistor. When power is
supplied by the external power supply, or when the connected battery does not have a battery ID or
thermistor, the battery ID and the battery thermistor must be faked. In order to fake this, turn the
battery ID and battery term switches to ON position.

DC Power Input Jack J500
The Open-Q2500 development kit power source connects to the 12V DC power supply jack J500.
Starting from the power jack, the 12V power supply branches off into different voltage rails via step
down converters on the carrier board and PMIC on the SOM.
