How to Use

Step 1. Download the Official image

1. Download Raspbian Official Image
   Download URL: https://www.raspberrypi.org/downloads/raspbian/
   Username: pi Password: raspberry
2. Download Ubuntu Mate Official Image
   Download URL: https://ubuntu-mate.org/download/
   The username and password can be set by yourself after startup
3. Download Kali Official Image
   Download URL: https://www.offensive-security.com/kali-linux-arm-images/
   Username: kali (The old version is root) Password: kali(The old version is toor)
4. Download Retropie Official Image

   Username: pi Password: raspberry

Step 2. Burn Official Image

1. Download and install tool software
   (If they are already installed, this step can be ignored) SD card format software SDCard Formatter download URL :
   https://www.sdcard.org/downloads/formatter_4/
   Image burning software Win32DiskImager download URL:
   https://sourceforge.net/projects/win32diskimager/
2. Format SD card
   Insert the SD card into the card reader -> Insert the card reader into the computer -> Open the SDFormatter software -> Select the SD card -> Select quick format (generally select quick format; other options can be selected according to your own needs) -> Click the Format button -> Select “Yes” -> Click OK after formatting.
3. Brun Image
   Open the Win32DiskImager software -> Select the image file to be burned (xxx.img ) -> Select the SD card -> Click the “write” button -> Select “Yes” -> Wait for the burning to complete (the whole process lasts about 10 minutes)

Step 3. Modify the “config.txt” configuration file
Open the “config.txt” file in the root directory of the SD card on the computer. Add the following at the end of the file, save and exit.
max_usb_current=1
hdmi_force_hotplug=1
config_hdmi_boost=7
hdmi_group=2
hdmi_mode=87
hdmi_drive=1
display_rotate=0
hdmi_cvt 1280 800 60 6 0 0 0

• Handle with care; use anti-static precautions.
• Avoid static discharge—use proper ESD protection when handling.
• Keep connector contacts dust-free.
• Store in a dry, temperature-controlled area.
• Don’t touch exposed electronic contacts with bare hands.
• Ensure good ventilation in the final device/enclosure.

Safety Tips

• Disconnect power before installing/removing module.
• Use only compatible carrier boards/power supplies.
• Protect from water, moisture, and conductive materials.
• Don’t force connections; insert gently.
• Use ESD protection during handling.
• Ensure cooling for high-load use.
• Never modify connections while powered.
