  • The B-L475E-IOT01A Discovery kit for IoT node allows users to 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 MCUs based on Arm® Cortex®-M4 core with 1 Mbyte of Flash memory and 128 Kbytes of SRAM, in LQFP100 package
    • 64-Mbit Quad-SPI (Macronix) Flash memory
    • Bluetooth® V4.1 module (SPBTLE-RF)
    • Sub-GHz (868 MHz or 915 MHz) low-power-programmable RF module (SPSGRF-868 or SPSGRF-915)
    • 802.11 b/g/n compliant Wi-Fi® module from Inventek Systems (ISM43362-M3G-L44)
    • Dynamic NFC tag based on M24SR with its printed NFC antenna
    • 2 digital omnidirectional microphones (MP34DT01)
    • Capacitive digital sensor for relative humidity and temperature (HTS221)
    • High-performance 3-axis magnetometer (LIS3MDL)
    • 3D accelerometer and 3D gyroscope (LSM6DSL)
    • 260-1260 hPa absolute digital output barometer (LPS22HB)
    • Time-of-Flight and gesture-detection sensor (VL53L0X)
    • 2 push-buttons (user and reset)
    • USB OTG FS with Micro-AB connector
    • Expansion connectors:
      • Arduino™ Uno V3
      • PMOD
    • Flexible power-supply options:
      • ST LINK USB VBUS or external sources
    • On-board ST-LINK/V2-1 debugger/programmer with USB re-enumeration capability: mass storage, Virtual COM port and debug port
    • Comprehensive free software HAL library including a variety of examples, as part of the STM32Cube MCU Package
    • Support of a wide choice of Integrated Development Environments (IDEs) including IAR, Keil®, GCC-based IDEs, Arm® Mbed Enabled
    • Arm® Mbed online (see http://mbed.org)
