This kind of car-mounted black box is popular on the market, which can track the driving information and location of the vehicle at any time; and it is very convenient to install, and there is no trace after installation. In fact, this so-called black box is something called GPS TRACKER, which is translated into GPS tracker in Chinese.
The installation of the GPS tracker is very simple, just connect the lead wire from the tracker to the positive and negative poles of the battery, the specific wiring can be determined according to different car models. There is also a fuse on the positive line of this tracker, which can effectively protect the GPS tracker in the case of unstable vehicle voltage.
As long as the positive and negative lines of the vehicle are found, the tracker can be connected. In order to enable the tracker to obtain better GPS signals, we recommend installing the tracker under the front console trim panel under the front windshield or near the air conditioning duct.
Unpack the GPS tracker, you will find a SIM card supporting the GSM network on the front of the circuit board, which is used to transmit vehicle position data via GPRS. Next to the SIM card is a square GPS ceramic antenna.
Various important modules are gathered on the back of the circuit board. CPU and GPS chip are located on the back of the circuit board. This GPS tracker uses the third-generation GPS chip of SiRF, which is widely used in various GPS navigators, and it is fairly good in stability. In terms of CPU, manufacturers claim to use dual-core industrial-grade CPUs. Considering that the GPS tracker does not require a lot of data processing, in fact its CPU is likely to be a dual-core single-chip microcontroller of 32bit+8bit. Since the shield cannot be disassembled, we can only make such a guess.
