Introduction
The AVT50 is a compact GNSS tracker designed for a wide variety of vehicle tracking applications. It has multiple I/O interfaces that can be used for monitoring or controlling external devices.
Its built-in GNSS receiver has superior sensitivity and fast time to first fix. Seven-band LTE-FDD in Europe and GSM/GPRS 850/900/1800/1900 MHz allow the AVT50's location to be monitored in real time or periodically tracked by a backend server and mobile devices.
The built-in 6-axis accelerometer and gyroscope support driving behaviour monitoring and motion detection.

Install a SIM card
- Open the case and ensure the unit is not powered.
- Slide the holder right to open the SIM card holder.
- Insert the SIM card with the gold contact area facing down. Align the cut mark.
- Close the SIM card holder and the case.
Internal backup battery
AVT50 has an internal backup 150 mAh Li-ion battery for continued operation when external power is unavailable.
Power connection
PWR (PIN1) / GND (PIN2) are the power input pins. The input voltage range is 7 V to 90 V. The device is designed for common 12 V / 24 V / 48 V / 64 V / 72 V vehicle systems without external transformers.
Digital outputs
AVT50 has one digital output (OUT1). The output is open drain type with a maximum drain current of 150 mA and a built-in over-current PTC resettable fuse.
