What is ELM327?

Remarkable technology from ELM electronics, ELM327 is a microcontroller programmed to translate the OBD interface you have in your vehicle. This interface is quite popular for its compatibility with a wide range of OBD2 protocols.

It is equipped with three major components, including a chip, set of electric voltage adapters, and set of voltage adapters for PC. The ELM327 chip is basically the main integrated circuit that engineers the translation of information from the car's ECU to a format that can be processed in a computer. Similarly, the electric voltage adapters work in the identification of various OBD2 systems. In the end, voltage adapters are responsible for generating communication between the adapter and the PC.

Are All ELM327 Scanners the Same?

Most ELM327 scanners on the market follow the same procedure of connectivity and usage. However, two models may look alike but can be entirely different in certain specifications.

Bluetooth Connectivity

Some ELM327 scanners do not offer a stable Bluetooth functionality, as they are deprived of this feature. On the other hand, OBD2 scanners equipped with built-in Bluetooth capability to provide wide coverage and ultimately enhance the mobility of the device.

Platform Support

Not all ELM327 scanners have the ability to support all working platforms in order to perform diagnosis. Some scanners are best-suited for iOS systems and require a computer device to provide accurate measurements. Similarly, scanners having compatibility with Windows on PCs do not work efficiently with Android systems.

On the other hand, nowadays, you will also find many improved versions on the market that are efficient enough to support all systems and keep you updated on your car’s status.


Just like some scanners are best suited for a particular operating system, they require the availability of a specific app to activate the operation.

From the above discussion, we have concluded that not all ELM327 scanners are the same. Some are ideal for iOS systems, while others are good for Android systems. However, in our opinion, we recommend you go for an advanced version that shows compatibility with all operating systems and also features Wi-Fi and Bluetooth capabilities to ensure a valued purchase.

What Should I Look For When Buying an ELM327 Scanner?

If you ever intend to buy an ELM327 scanner, you’ll find a plethora of options available in the market. This makes the purchase quite confusing and extremely tiresome. Therefore, we have summarized a set of features that must be focused whenever you are in the market for a scanner.


An important feature that you must look for in an ELM327 scanner is the quality of construction. Always go for a model composed of high-quality materials and built to perform, even under tough conditions.


This is the most important feature for any beginner to get the best results possible. Opt for a model that is handy and comes with a user-friendly design so you won’t get confused while working with it for the first time.


One of the most significant features of any great ELM327 scanner is its ability to work with a wide range of vehicles, including US-based or non-US models. From Mazda to Ford, it must be capable of diagnosing the problem in each vehicle. Additionally, it should be suitable for numerous subsystems of your automobile vehicle to check the faults seamlessly. The app should also be compatible with your devices, whether iOS, Android, or Windows.


Since not everybody can afford to spend tons of cash on a scanner, it is recommended to choose a model that features all essential specifications, without feeling heavy on the pocket.
