How to choose the right Arduino board

How to choose the right Arduino board should be a headache problem for many green hands.

As we know the Arduino development board is a big family. There are dozens of different development boards listed on the official website of Arduino.

Especially the Arduino official team decided to use a Creative Commons (CC) license to keep the idea of openness alive.Under the CC license, anyone is allowed to produce and sell copies of the Arduino development board without paying royalties to the Arduino official, or even obtaining an official license from the Arduino, just to explain the contribution of the Arduino team and to keep the name of the Arduino.

Therefore, there are two main kinds of development boards on the Internet, one is the official board produced by Arduino officially, and the other is the clone board made and sold by other manufacturers using the design of the Arduino team.

If you want to develop your own Arduino boards, recommend to use EasyEDA to design the board, and you can generate the files to manufacture in JLCPCB, you can get the PCB sample by only $2 and they also provide PCB assembly service by only $7, which will help save lots of money.

As far as I know, the first development board of almost Arduino enthusiasts is Arduino Uno R3.

This development board can be said to be the most cost-effective one of all products, and also the most suitable for beginners to learn to use the development board.

The Arduino Mega development board is similar to the Arduino Uno but is twice the size of the Uno development board.

If you are developing a project that needs more pins than Uno to control external devices and collect sensor data, Mega can meet your needs. In addition, Mega has more hardware serial interfaces for serial communication with more external devices.

Of course, more features mean the Mega is also more expensive than Uno.

Whether you choose Mega or Uno, it depends on the specific needs of the project you are building.

Arduino Nano "board", As the name suggests, is only about a third the size and weight of Uno.

Despite its small size, the Nano is not easy to handle.

To have the same core microcontroller as Uno (ATmega 328), the Nano has slightly more pins than Uno.

If your project has the size and weight requirements that make Uno unsuitable, the Nano is a good choice.

These development boards can be said to be the most popular products of the Arduino family.

In addition to these, there are many other products of the Arduino family, some of which can be used for artificial intelligence, cloud computing, and image recognition, while others are better at theInternet of things applications.

Go to get the one most suitable for your project, you had better read the datasheet of them carefully, I will make a serial of articles to show the difference of these boards in the near future.Looking forward to it~
