This design is a upgraded version of the VALTRACK series of vehicle tracking devices. It has been upgraded to support 4G-LTE-CAT1/3G/2G networks all over the globe for cellular connectivity and Bluetooth 5.0 for configuration of parameters and over the air (OTA) firmware update using Android application.

VALTRACK-V4-VTS comes with multiple options, with Global version, European version and Asian version. Its fully configurable using Bluetooth and can send location pings using HTTP (POST) or MQTT protocol to the any server configured.

Model No :

• VALTRACK-V4-VTS [IO-INT-LTE]

Operating Voltage :

• Main Power Input : 12V to 42V DC to be connected to 12V Lead Acid Battery. (Has Reverse Polarity Protection)
• Backup Battery Input : 3.7V to 4.2V DC to be connected to a single cell 3.7V-4.2V Li-Po or Li-Ion Battery. (Doesn't have Reverse Polarity Protection) (Battery is not included due to hazardous goods shipping restrictions)
• MP2617 Charger chip is used to handle the battery charging.

Dimensions With Enclosure

• Length: 52mm Width: 65mm Height: 30 mm

PCB Dimensions

• Length: 34mm Width: 43mm Thickness: 1.6 mm

Cellular module :

• SIM7600G - LTE 3G 2G - For Global use

SIM Connector :

• Nano SIM connector

Default Location :

• SE868K3AL GNSS module comes with inbuilt patch antenna External Antenna

• SIM7600x has inbuilt GNSS hardware which needs external active antenna [Bias is already provided to the GNSS U.FL connector] but needs a special firmware for using this and is only available on request.

Operating Modes :

• HTTP, MQTT over TCP

Configuration Methods

• Bluetooth 5.0 available on board can be used to configure the device using the VALTRACK-V4 Setup application.

Processor:

• STM32WBxx ARM Cortex M4 , 64MHz

Motion Sensor:

• LIS3DH 12-bit, 3-axis Accelerometer

Memory:

• 16KB I2C EEPROM for storing parameters.

Antennas :

• Cellular Antenna: U.FL Connector , 1.5 dBi gain Flexible PCB antenna comes attached
• GNSS Antenna: Inbuilt patch antenna for SE868K3AL module and U.FL Connector for SIM7600x GNSS (Not available by default)

Flashing options

• SWD Debug port available on a FFC connector [10 pin, 0.5mm pitch ].
• MCU can be flashed Over The Air (OTA) using Bluetooth interface

Enclosure:

• Device ships in a standard IP67 rated enclosure.

Getting Started

Opening the enclosure

• You need to remove the four screws present in the bottom of the enclosure to open it. Use a star head screw driver.

Inserting the SIM card

• Get a Nano-SIM card and insert it into the boards push-pull type SIM card slot. [Power should not be connected to the device during SIM card insertion]

LED Indicators

• Once the device is powered ON, The LED will show up and start with all RED .
• Once the SIM is registered to the network, the NETWORK LED turns GREEN .
• Once the GNSS module gets a location sync, the LOCATION LED turns GREEN .
• After 30 seconds of inactivity, all LED will turn OFF to save power and turn ON again on movement detected by Accelerometer.
• POWER LED remains RED all the time

Firmware

• By default Motion triggered firmware is loaded where the device keeps sending location pings at set ping interval and goes to sleep after 5 minutes of inactivity to save power.
