The Suntech ST25T/PM is a multifunctional port expander designed to be used in conjunction with the ST3300 or ST4300 tracking devices. This device provides accurate information about fuel level and other additional functions. One of the standout features of the ST25T/PM is its power-saving mode, which allows for lower battery consumption and therefore, greater autonomy. This is especially useful in long-term tracking applications where a reliable and durable device is required.

The ST25T/PM is powered through a 5V power source from the ST3300 or ST4300, which simplifies installation and eliminates the need for additional batteries. Additionally, it has efficient power consumption, with 37.5mA in recurrent active mode and only 3.1mA in suspension mode. With a temperature range of -45°C to +85°C, the ST25T/PM is capable of operating in extreme conditions, making it an ideal choice for applications in adverse environments. Its compact size of 53 x 55 x 19 mm and lightweight design of 32g (without event cables) make it easy to install on different types of vehicles and equipment.

The ST25T/PM also offers the ability to remotely update its firmware using the Over-The-Air (OTA) function through the ST600M or ST4300, ensuring that the device is always up to date with the latest improvements and features.
