H A Dstm32.rst1 STMicroelectronics STM32 boards (``netduino2``, ``netduinoplus2``, ``olimex-stm32-h405``, ``stm32vl…
4 The `STM32`_ chips are a family of 32-bit ARM-based microcontroller by
7 .. _STM32: https://www.st.com/en/microcontrollers-microprocessors/stm32-32-bit-arm-cortex-mcus.html
9 The STM32F1 series is based on ARM Cortex-M3 core. The following machines are
12 - ``stm32vldiscovery`` STM32VLDISCOVERY board with STM32F100RBT6 microcontroller
14 The STM32F2 series is based on ARM Cortex-M3 core. The following machines are
17 - ``netduino2`` Netduino 2 board with STM32F205RFT6 microcontroller
19 The STM32F4 series is based on ARM Cortex-M4F core, as well as the STM32L4
20 ultra-low-power series. The STM32F4 series is pin-to-pin compatible with STM32F2 series.
21 The following machines are based on this ARM Cortex-M4F chip :

H A Db-l475e-iot01a.rst1 B-L475E-IOT01A IoT Node (``b-l475e-iot01a``)
4 The B-L475E-IOT01A IoT Node uses the STM32L475VG SoC which is based on
5 ARM Cortex-M4F core. It is part of STMicroelectronics
6 :doc:`STM32 boards </system/arm/stm32>` and more specifically the STM32L4
7 ultra-low power series. The STM32L4x5 chip runs at up to 80 MHz and
8 integrates 128 KiB of SRAM and up to 1MiB of Flash. The B-L475E-IOT01A board
15 Currently B-L475E-IOT01A machines support the following devices:
17 - Cortex-M4F based STM32L4x5 SoC
18 - STM32L4x5 EXTI (Extended interrupts and events controller)
19 - STM32L4x5 SYSCFG (System configuration controller)
