1. If there is any spare GPIO pin available on the microcontroller, please connect it to a separate pad on the PCB.
2. One VCC pad and one GND pad are also required separately on the PCB.
3. When the spare GPIO pin detects VCC (high signal), an alarm should trigger in the smartwatch.
4. The smartwatch should vibrate and blink the display with the message "EMERGENCY".
5. This is a simple modification. Please let us know the minimum quantity that we are required to order as samples
6. After successful testing, we plan to order 3000 to 5000 units per month.
