  • With the B-L4S5I-IOT01A Discovery kit for IoT node, users develop applications with direct connection to cloud servers. The Discovery kit enables a wide diversity of applications by exploiting low-power communication, multiway sensing and Arm® Cortex®-M4 core-based STM32L4+ Series features. The support for ARDUINO® Uno V3 and Pmod™ connectivity provides unlimited expansion capabilities with a large choice of specialized add-on boards.

    Key Features

    • Ultra-low-power STM32L4+ Series STM32L4S5VIT6 microcontroller based on the Arm® Cortex®-M4 core with 2 Mbytes of Flash memory and 640 Kbytes of RAM in LQFP100 package
    • 64-Mbit Quad-SPI Flash memory from Macronix™
    • Bluetooth® 4.1 module (SPBTLE-RF) from STMicroelectronics
    • 802.11 b/g/n compliant Wi-Fi® module (ISM43362-M3G-L44) from Inventek Systems
    • Dynamic NFC tag based on ST25DV04K with its printed NFC antenna
    • 2 digital omnidirectional microphones (MP34DT01) from STMicroelectronics
    • Capacitive digital sensor for relative humidity and temperature (HTS221) from STMicroelectronics
    • High-performance 3-axis magnetometer (LIS3MDL) from STMicroelectronics
    • 3D accelerometer and 3D gyroscope (LSM6DSL) from STMicroelectronics
    • 260-1260 hPa absolute digital output barometer (LPS22HB) from STMicroelectronics
