AT&T IoT Starter Kit (LTE-M, STM32L4) The LTE-M, STM32L4 version AT&T IoT Starter Kit enables designers to easily develop and prototype cellular connected IoT devices utilizing AT&Ts 4G LTE-M 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 versatile two board IoT solution comprised of a microcontroller based carrier board (STM32L475 IoT Discovery board) and a cellular connectivity daughter card (Avnet M14A2A LTE-M Cellular Shield). The STM32L475 IoT Discovery board functions as the host processor and provides an Arduino compatible R3 expansion interface for the LTE-M cellular modem, which plugs into the Arduino R3 connectors, forming a compact two board sandwich. The microcontroller IoT board contains an STM32L475VG microcontroller based on an ARM Cortex-M4 MCU (running at 80 MHz, with 1MB Flash memory, 128 KB RAM), plus 64-Mbit QSPI Flash memory, multiple radio modules (Bluetooth v4.1, Sub-GHz LPRF, Wi-Fi 802.11 b/g/n), dynamic NFC tag and security features, multiple sensors (temperature, humidity, magnetometer, 3D accelerometer, 3D gyroscope, barometric pressure, time-of-flight / gesture detection) and two digital microphones. The 4G LTE-M cellular shield is built around an M14A2A modem module from WNC (Wistron NeWeb Corp) configured for LTE-M operation. Other features include: onboard temperature and humidity sensor, multiple serial interfaces to the host controller, plus an SMA-connected external antenna and USB-connected KIT INCLUDES AC/DC 5V power supply.
