Espotel LoRa Module

Contents

Hardware

Platform :ref:`platform_ststm32`: The STM32 family of 32-bit Flash MCUs based on the ARM Cortex-M processor is designed to offer new degrees of freedom to MCU users. It offers a 32-bit product range that combines very high performance, real-time capabilities, digital signal processing, and low-power, low-voltage operation, while maintaining full integration and ease of development.

Microcontroller STM32F411RET6
Frequency 100MHz
Flash 512KB
RAM 128KB
Vendor Espotel

Configuration

Please use elmo_f411re ID for :ref:`projectconf_env_board` option in :ref:`projectconf`:

[env:elmo_f411re]
platform = ststm32
board = elmo_f411re

You can override default Espotel LoRa Module settings per build environment using board_*** option, where *** is a JSON object path from board manifest elmo_f411re.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:elmo_f411re]
platform = ststm32
board = elmo_f411re

; change microcontroller
board_build.mcu = stm32f411ret6

; change MCU frequency
board_build.f_cpu = 100000000L

Uploading

Espotel LoRa Module supports the following uploading protocols:

  • blackmagic
  • cmsis-dap
  • jlink
  • stlink

Default protocol is stlink

You can change upload protocol using :ref:`projectconf_upload_protocol` option:

[env:elmo_f411re]
platform = ststm32
board = elmo_f411re

upload_protocol = stlink

Debugging

:ref:`piodebug` - "1-click" solution for debugging with a zero configuration.

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

You can switch between debugging :ref:`debugging_tools` using :ref:`projectconf_debug_tool` option in :ref:`projectconf`.

Espotel LoRa Module does not have on-board debug probe and IS NOT READY for debugging. You will need to use/buy one of external probe listed below.

Compatible Tools On-board Default
:ref:`debugging_tool_blackmagic`    
:ref:`debugging_tool_cmsis-dap`    
:ref:`debugging_tool_jlink`    
:ref:`debugging_tool_stlink`   Yes
