Assembling the AT&T IoT Kit Hardware
The hardware is delivered as two separate boards. Use the following instructions to connect the
boards.
1. Plug the Avnet Cellular shield onto the Arduino connectors on the FRDM-K64F board.
2. Plug the supplied AT&T SIM card into the SIM socket (X3) on the shield.
3. Screw the two antennas to the shield SMAs connectors (X1, X2).
4. The cellular shield requires 5V power supplied by the included AC/DC power adapter. It is not
recommended to use a laptop USB port for this power source due to the limited power capabilities of
most USB ports. Plug a microUSB cable into the 5V USB shield power (X5) on the Cellular shield and
connect the other end of the cable to the provided AC/DC supply. LED1 illuminates light green.
5. Plug a microUSB cable into the SDA USB (J26) port on the FRDM-K64F board. Connect the other
end of the cable to a USB port on your laptop. The kit should enumerate as a standard
MBED
USB
drive.
