Equipment List
• Raspberry Pi Model 4B: 8G RAM with SSD, dual monitors, keyboard, and mouse with internet connection as a development system.
• Your embedded system code can run on a Model 4B with 4G RAM.
• I used a SanDisk 32GB Ultra MicroSDHC UHS-I with A1 - very important to have a good microSD card if you are not running an SSD.
• A touch screen display. I used a 5" capacitive touch screen.
• Breadboard, wires, and electronic components.
• Adequate power supply, heat sinks, and cooling for Pi.

Software List
• Use the Raspberry Pi Imager to set up the microSD card with Raspberry Pi OS 64-bit.
• Update and upgrade the system OS on the Pi (sudo apt update and sudo apt full-upgrade)
• Install Snap and then Flutter https://snapcraft.io/docs/installing-...
• In a terminal window: flutter --version (this will download/install more and takes time).
• After this is done, in the terminal window run flutter doctor -v and this will install more and take time.
• Install VS Code by opening a terminal window, sudo apt install code and then enter.
• Clone (or download and extract) the project to the folder of your choice on your Pi.
