A: Firstly, insert the C1220 button battery. run the following command:

sudo nano /boot/config.txt
#Then change the line: dtoverlay=i2c-rtc,pcf8563 to dtoverlay=i2c-rtc,ds1307

#Test RTC
#Display the current time of the Raspberry Pi
#Write the time of Raspberry Pi to DS1307
sudo hwclock -w

#Read the time of DS1307
sudo hwclock -r

Q: Why PiKVM-A3/A4 does not show the video?


  • Double-check that the video capture device is connected correctly and tightly. For the CSI bridge, this should be exactly the camera port;
  • Some laptops do not output any signal until you switch the output (usually via the FN + and an F5 key on the keyboard).
  • Your computer may have turned on sleep mode for the monitor. Move the mouse to turn it off.
