STMicroelectronics STEVAL-MKIT01V1

Overview

STEVAL-MKIT01V1 from STMicroelectronics is a compact, ready-to-use development kit for the STM32L476RG microcontroller, featuring an integrated MEMS accelerometer (LSM303AGR), gyroscope (LSM6DSL), magnetometer (LIS3MDL), and environmental sensors (HTS221, LPS22HB). It supports USB-based debugging and programming via ST-LINK/V2-1, and includes Arduino Uno R3-compatible headers for rapid prototyping in ultra-low-power IoT edge nodes.

For engineers reviewing the STEVAL-MKIT01V1 datasheet, STEVAL-MKIT01V1 pinout, STEVAL-MKIT01V1 application, or STEVAL-MKIT01V1 equivalent, key considerations include its dual-core sensor fusion capability, 1.71–3.6 V supply range, 80-pin LQFP package mapping, and support for real-time sensor data streaming over USB CDC ACM virtual COM port.

Technical Context

The kit implements a full-featured evaluation platform centered on the ARM Cortex-M4F core running at up to 80 MHz with 1 MB Flash and 128 KB SRAM. Sensor subsystems are connected via dedicated I²C and SPI buses, each with configurable interrupt routing and hardware FIFO buffering.

Power management leverages the STM32L476's multiple low-power modes (Stop 2, Standby with RTC), enabling sub-1 µA shutdown current. The onboard ST-LINK/V2-1 provides SWD debug interface, UART bridge, and mass storage programming mode - all accessible without external tools.

FAQ

Does STEVAL-MKIT01V1 support Bluetooth Low Energy connectivity out of the box?

No. The board does not include a BLE radio IC or antenna. However, it provides UART and GPIO resources compatible with ST's SPBTLE-RF module or third-party BLE modules via Arduino headers. Firmware-level integration requires external BLE stack implementation or use of ST's BlueNRG-M2SP companion board.

Can the onboard ST-LINK/V2-1 debug STM32 microcontrollers on external target boards?

Yes. The ST-LINK/V2-1 can be used as a standalone debugger by disconnecting the SB13/SB14 jumpers and wiring SWDIO, SWCLK, NRST, and GND to an external target. It supports voltage adaptation from 1.65 V to 3.3 V and is fully compatible with STM32CubeProgrammer and STM32CubeIDE.

What software tools are officially supported for firmware development on STEVAL-MKIT01V1?

ST officially supports STM32CubeIDE (free Eclipse-based IDE), STM32CubeMX (graphical initialization code generator), and STM32CubeL4 firmware package. Keil MDK-ARM and IAR Embedded Workbench are also qualified and listed in ST's toolchain compatibility matrix.

Is the LSM6DSL gyroscope configured for high-performance or low-power mode by default in the factory firmware?

The factory-loaded demonstration firmware configures the LSM6DSL in high-performance mode (ODR = 104 Hz, full-scale ±2000 dps), with hardware FIFO enabled and interrupt routed to MCU GPIO. Register settings are visible in the provided STM32Cube function calls within the "Drivers/BSP/Components/lsm6dsl/lsm6dsl_reg.c" source file.
