A:Regarding the low voltage alarmwarning issue:

1. Please carefully check whether your hardware installation is firmly installed secure and whether if the ejector pin is in good pogo pins are making proper contact. Some We have had cases where customers have found that loose brass standoffs caused poor contact with the copper pillar is not tightenedpogo pins, resulting in poor ejector pin contact and leading to the low voltage promptwarning.

2. It may be caused by an OS update. Please confirm whether you have recently updated the OS recently? Or or if your OS system will updates automatically update.

3. Please run the command: <code>vcgencmd pmic_read_adc </code> and tell provide us with the result. Alternatively, or use a multimeter to measure the voltage value of PIN2.  As shown in the figure
