This connection is not useful when using a system load, charger, or
a power source (battery or external power supply). The red wire of
the EV2300 connector gives access to a low-power, 3.3-V output
when connected to HDQ section of EV2300. Shield this wire when
it is not in use to avoid contacts with other connections such as
ground.
