5 Installing OS (optional)

  • If you are purchasing a device without Raspberry Pi 4 and SD card, the device does not come with an operating system by default. Raspberry Pi 4 needs to be installed first, then you need to install os. Our company supports to install the OS by installing the standard Raspberry Pi OS first, and then install the Firmware package.

  • If you are purchasing a device with Raspberry Pi 4 and SD card, the device is shipped with an operating system by default. If the OS is corrupted during use or the user needs to replace the OS, it is necessary to re-download the appropriate system image and install it. Our company supports to install the OS by installing the standard Raspberry Pi OS first, and then install the Firmware package.

The following section describes the specific operations of image download, SD card flashing and installation of Firmware packages.

TIP

Please make sure you install our Firmware package after you install Standard Raspberry Pi OS, otherwise the display and touch won't work.
