The IoT starter kit, LTE-M, STM32L4 from Avnet using AT&T includes an IoT Discovery board from STMicroelectronics. The board reduces the complexity of LTE-M device development by bringing together all the elements required to develop and prototype secure, cost-effective, and reliable IoT devices connected to AT&T’s 4G LTE-M network.
The two-board LTE-M solution includes the STM32L475 IoT Discovery board and a cellular connectivity card from Avnet, as well as a modem module from WNC. They are capable of LTE-M operation, and access to lower-cost licensing options for Arm Keil MDK microcontroller software development tools. The IoT Discovery board is an “out-of-the-box” cloud-ready connectivity board for IoT nodes. It features the ultra-low-power Arm Cortex-M4 processor-based MCU (clocked at 80 MHz, with 1MB Flash memory, 128 KB RAM).
The microcontroller-based carrier board functions as a low-power host processor that integrates onboard environmental sensors, motion, gesture and time-of-flight sensors, digital microphones, Bluetooth low-energy, a sub-GHz transceiver and Wi-Fi, as well as Pmod and Arduino Uno V3-compatible expansion connector interfaces.
AT&T’s M2X Data Services and Flow Designer enable designing with cloud-based services. The kit comes with a free 90-day license and reduced-cost, 6-month license for Arm Keil MDK software development tools, which enable rapid development and advanced debugging capabilities.
The Avnet 4G LTE-M cellular modem board stacks onto the ST Discovery board via Arduino Shield connectors to form a compact two-board assembly. A 3FF micro SIM connector accommodates the provided AT&T Starter SIM for easy connection to the Internet. Read more…
