Avnet's AT&T Cellular IoT Starter Kit enables designers to easily develop and prototype cellular connected
IoT devices utilizing AT&T’s 4G LTE network. The kit includes all the elements required to collect sensor data,
connect to the AT&T network, and utilize various cloud services for the management, storage, and analytics
of a connected IoT device.
The Starter Kit features a two board solution comprised of a microcontroller-based carrier board and a
pluggable, cellular connectivity daughter card. NXP’s Freedom FRDM-K64F microcontroller carrier board
acts as the main host processor, providing an Arduino compatible R3 expansion slot. The Avnet created 4G
LTE cellular shield plugs into the Arduino R3 slot, forming a small 3.25” x 2” x 1” two board “sandwich”. The
FRDM-K64F board contains a Kinetis K64F microcontroller, based on an ARM® Cortex®-M4 MCU running at
120 MHz, with 1MB Flash memory, 256 KB RAM, Ethernet port, USB port, microSD card slot, and a 6-axis
digital accelerometer and magnetometer. The 4G LTE cellular shield is built around the low-cost Wistron
NeWeb Corp. (WNC) M14A2A LTE Cat-1 modem module. The shield supports primary and diversity external
antenna connections through two onboard SMA connectors, a 3FF microSIM connector, a temperature and
humidity sensor, and multiple serial link options to the host controller.
Application development is supported by AT&T’s M2X Data Services and Flow Designer, which provides a
scalable, reliable and highly secure environment for IoT-focused solutions. Additional cloud services from
industry partners are also available. The hardware platform is enabled for ARM® mbed, allowing for
development in a cloud-based environment, or in a locally supported environment through either the Open
Source SDA or JTAG connection to the baseboard.
