Interfaces and Electrical Data

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.

International Data Roaming by JT

The C030-U201 IoT Starter Kits come with International Data Roaming bundled with 50 MBytes of data for the first 3 months .

The International Data Roaming service is provided by JT . To turn on the International Data Roaming service, please register your board's eUICC(Embedded SIM) IMSI through JT IoT Registration web site.

Information

How to find C030-U201 IMSI Number

The eUICC(Embedded SIM) IMSI number is written on the label at the back of the C030-U201. The IMSI number is also coded on the QR-Code label on top of the Ethernet connector of the C030-U201.

If the IMSI number cannot be read from these labels, the example program for reading the modem IMEI and eUICC/SIM IMSI could be used. The example prints out the IMEI and IMSI numbers of the board to the serial debug console.

Power Supply and LiPo Battery

During the RF transactions, SARA-U201 module of C030-U201 Application Board demands higher currents than a USB 2.0 Master Port could provide. If the C030-U201 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-U201 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"
