External Power
There are a few reasons why you may want to provide external power, including higher IR transmit power,
changing to a different voltage, or using a battery to go "wireless." To provide external power, use the
following procedure.
1. Disconnect BOOST-IR power from the LaunchPad power source
(a) Option 1: Remove the 3V3 jumper on the LaunchPad isolation block
In this case, the MCU is also powered by the external source; make sure that the voltage is within
the MCU device voltage operation specification.
(b) Option 2: Remove R1 on the BOOST-IR to completely disconnect LaunchPad and BoosterPack
power
(i) In this case, the LaunchPad must provide power to its own MCU.
(ii) If the LaunchPad and BoosterPack have different operating voltages, IR communication may
not function properly.
2. Connect the external power supply.
After these steps are complete, you should be able to operate the IR BoosterPack with an external
voltage.
