I just got the board today. I was almost disqualified because I was a substitute. I still want to thank the staff. Let's take a look at the packaging first.
The whole box is very large, and the Mier logo is very conspicuous. Mier should be one of the earliest embedded development board solutions in the industry. He has solutions for many Linux boards. I have also had some experience with them.
After unpacking, there is a quick guide inside, which can be used to perform a simple test on the board in the early stage, and also to understand the hardware structure of the board.
There is also a packing list inside to let you know what is included.
Next is the development board, which is packed in an anti-static bag. We can learn the model parameters of the board through the label on the packaging paper.
Our board should have 256MB of memory and 256MB of Nand Flash storage. Of course, you can choose a higher configuration.
Other accessories inside are a power supply with multiple adapters, which meet the requirements of other countries in the world. It also comes with a type-C debugging cable, the board's studs, and an adapter power connector.
Let's take a closer look at the board. First of all, many interfaces are brought out through pin headers, which will facilitate our development and wiring in the future. This is equivalent to giving us a basic model for building and developing, and we can add bricks and tiles according to our own requirements later.
The core board is also equipped with a shielding cover. At the same time, the model is also engraved by laser. The whole board is made of sub-black gold, which looks very comfortable.
Uncover the mysterious shell, and you will find three core components inside: memory, storage, and CPU. There is also a power management chip, which should be the same as the one used on the official ST board.
Then our CPU should be a single-core A7, which is enough for the evaluation. If you want to use a dual-core A7 later, you can change the core board.
The core board is also relatively thick, but I don't know why. Is it because they are afraid of deformation due to the large size of the core board? This is the end of the unboxing for now, and I will continue to experience it later.
