external power supply and/or LiPo battery is recommended

Due to the USB current limitation, optimal RF performance can be achieved only by supplying the board either through the "Aux 5V USB" connector or the VIN pin of the Arduino® UNO R3 interface. Other alternative is to use a LiPo Battery connected through the "LiPo Battery" connector. Please refer to Power Supply and LiPo Battery section below.

Power Supply and LiPo Battery

During the RF transactions, SARA-N211 module of C030-N211 Application Board demands higher currents than a USB 2.0 Master Port could provide. If the C030-N211 Application Board is powered from a single USB 2.0 port, a Brown Out could be experienced during RF transactions. This situation is observed as premature board reset and/or application interruption. To overcome such situation, the C030-N211 Application Board could be powered with a high current PSU through purpose built "Aux 5V USB" connector. Another, solution is to connect a LiPo battery to the "LiPo Battery Connector"
