Dear valued customers,

We are delighted to announce that our parking lot management system's mainboard has undergone careful enhancements and now boasts six significant upgrades. These improvements are designed to enhance the system's performance and reliability, providing you with a better user experience.

Here are the enhancements we have made:

> Increased Signal Input Indicators
We have added signal input indicators to help you quickly understand the communication status between external devices and the control board.
This means you can easily monitor the system's operation.

> Added Discharge Capacitors
We have increased the discharge capacitors, reducing the time needed for the control board to power up again after a power outage.
This ensures the system returns to normal operation more swiftly.

> Added DC 5V Output
We have introduced a new DC 5V output interface, making it convenient to provide power input for external devices.
This allows your devices to receive the required power supply more easily.

> Enabled Battery Functionality
We have resolved the issue of time not being saved after a power failure and enabled battery functionality.
This means your settings and data will be preserved even in case of a power outage.

> Added Temperature Sensor
We have incorporated a temperature sensor, providing possibilities for future feature expansions.
The system can now intelligently respond to temperature changes, offering a more comfortable environment control.

> Shortened Buttons
We have reduced the length of buttons on the control board, minimizing the risk of manual damage.
This means you can use the system for a longer period without worrying about the durability of the buttons.

These upgrades make our parking lot management system more efficient, reliable, and user-friendly. We are committed to providing you with the highest quality products and services, and we hope these enhancements will enhance your experience.
