The mikromedia 5 for Tiva
™
board can be powered in four different ways: via two USB connectors using MINI-B USB cable provided with
the board
(CN9 or CN2)
, via battery connector using Li-Polymer battery
(CN3)
or via adapter connector using adapter power supply
(CN1)
. After you plug in the appropriate power supply turn the power switch ON
(SW1)
. The USB connection can provide up to 500 mA
current which is more than enough for the operation of all on-board modules and the microcontroller as well. If you decide to use external
power supply via adapter connector, voltage levels must be within
5-12 V DC
range. Power
LED ON (GREEN)
indicates the presence of
power supply. On-board battery charger circuit
LM3658SD-A
enables you to charge the battery over two USB connectors or via adapter
connector.
LED diode (RED)
indicates when battery is charging. Charging current is ~250 mA and charging voltage is 4.2 V DC.
