Cloud-Connectable Kit Enables Fast and Flexible IoT-Device Development

STMicroelectronics’ STM32L4 IoT Discovery kit (B-L475E-IOT01A) supports multiple low-power wireless standards and Wi-Fi, while integrating a complete collection of motion, gesture, and environmental sensors, unavailable on other kits in the market. The kit adds modules for Bluetooth low energy (BLE), sub-GHz RF, and Wi-Fi, with a dynamic NFC-tag IC with printed antenna to a high-performance, ultra-low power STM32L4 microcontroller all on the same board. The comprehensive selection of sensors includes a MEMS accelerometer and gyroscope IC and MEMS magnetometer for 9-axis motion sensing, a barometric pressure sensor, temperature/humidity sensor, two omnidirectional digital microphones, and a FlightSense proximity and gesture sensor.

 

The heart of the kit is an 80MHz STM32L475 32-bit microcontroller that combines the ARM Cortex-M4 core featuring DSP extensions, 1-MB on-chip Flash, and the company’s ultra-low-power technologies to help build smart IoT devices on a tight power budget. Equipped with the ST-Link debugger/programmer on-board, the STM32L4 Discovery kit IoT node does not need any external probe, and can be used with ARM Keil MDK-ARM, IAR EWARM, or GCC/LLVM-based Integrated Development Environments (IDEs) including free AC6 SW4STM32, or with mbed online tools.
