RAK7200 Helium Mapper

RAK7200 - S76G SiP (STM32l073RX, SX1276, CXD5603GF)

Building firmware for the RAK7200 powered by the AcSiP S76G SiP

Required software:

• Arduino IDE https://www.arduino.cc/en/software

• STM32CubeProgrammer https://www.st.com/en/development-tools/stm32cubeprog.html

• Install the Arduino IDE and STM32CubeProgrammer

• Start the Arduino IDE

  • Go to Tools > Board > Board Manager type STM32 in the filter your search... field
  • Click Install to install the current version of the STM32 Cores Board

• After the STM32 Cores Boards is installed exit and restart the Arduino IDE

  • Go to Tools > Board > STM32 Boards > Nucleo-64
  • Then select the microcontroller Tools > Board Part Number > Nucleo L073RZ
  • Then configure the environment:
    • Tools > U(S)ART Support > Enable (generic 'Serial')
    • Tools > USB Support (if available) > None
    • Tools > USB Speed (if available) > Low/Full Speed
    • Tools > Optimize > Smallest (Os default) or Fast (O1)
    • Tools > C Runtime Library > Newlib Nano (default)
    • Tools > Upload Method > STM32CubeProgrammer (serial)
    • Tools > Port > Select the port associated with the RAK7200}

When you have finished configuring the environment it should look similar to this:
