Salind 11 GPS Tracker – Made in Germany

I wanted to see how someone is building a GPS tracker in Germany, what different they are doing vs other designs available in the market so I did a review of Salind GPS Tracker which is made in Germany. You can check teardown of other GPS Trackers here.

The GPS Tracker comes in a nice premium packaging with micro USB charging cable, user manual.

You can open it easily by opening six screws.

Once you open them, large battery is visible and a small PCB board. What is the capacity of the battery? 10,000mAh gives 90days of stand by time as per their claim.

This is one of the simplest designs I have ever seen of a GPS tracker.

On the right hand side you see 6 circles that is nothing but magnet inside the enclosure, this allows device to be magnetically attached.

you can see the PCB antenna is attached to the enclosure.

The LDR you see at the center of the PCB is probably to detect if device is attached or not.

Enclosure + (4-cell in parallel) Battery, PCB antenna, GPS tracker circuit on the PCB.

Simple construction and assembly.

GPRS Tracker is built on Quectel MC25 2G module which has inbuilt GPS.

Micro USB interface is used for charging and the charger IC is TP4056 linear charger, low cost IC and widely used in various designs.

One slider switch is used for ON/OFF.

In the image below you can see RF cable is soldered on the PCB that connects to the antenna PCB on the other side.

On the other side of the PCB, you have Micro USB connector, SIM connector and Patch Antenna for the GPS.

Three LEDs are provided, one for GPRS, one for battery charging indication and one for GPS.

This is the enclosure side where SIM card and USB connector are connected.

Rubber cover is provided to protect from water splash and dust.

That’s all in this teardown.

I hope you found it interesting and learned something new today. I will write a new blog soon. Do share with your friends.
