3.4.1.1
AC Adapter Operation
When using an AC adapter, the adapter is connected to the power adapter connector (J230). The adapter supplies a constant 4.5
V, which is regulated to a nominal 4.1 V on the Developer Board.
3.4.1.2
DC Power Source Operation
You can use an external DC power supply by connecting it to the VCC (J201) and GND (J200) connectors.
The supplied DC input connectors must be attached to the Developer Board in order to use an external DC power source. Use
the red connector for VCC and the black one for GND. Connect the DC power source to these connectors using banana plugs,
alligator clips or wire.
The DC voltage applied through this connection should not exceed the recommended operational limits of 3 V to 4.2 V. In all
cases, the DC source input is protected from over voltage and reverse polarity, and includes a 2.5A protective fuse.
It is recommended to remove jumper P202 when using the DC power source. The DC power source should not be
!
used when other sources are connected.
Caution
3.4.1.3
Battery Operation
The Developer Board supports a battery power supply. The battery used must be a 3.6V lithium-ion cell, corresponding to
Motorola part number 0189727L01. The battery is an optional accessory.
When using a battery as the main power source, the AC adapter input operates as a battery charger, which connects to an
on-board battery charging circuit.
