There's a reason why everything goes up in price: demand outstrips supply.
Not to mention Raspberry Pi, many chips have increased in price, such as STM32, which rose by nearly 10 times at its peak last year.
So, a lot of interesting things happened.
For example: In the past, the boss who received the order was so happy that he couldn't sleep, but now the boss who received the order was so worried that he couldn't sleep .
The price of chips has risen too fast, and the profit of many products is only a few dollars. If you increase the price by 10 times at once, the customers must think that you are insulting their IQ.
If you don't do it, you may lose this customer, so it's too difficult..
There are also some things. In the past, I didn’t make any money from making products, but instead sold the chips that I stocked for products and made a lot of money.
Then why the price increase?
1. The impact of the epidemic
This is the closest impact to the world. The epidemic has caused many companies to suspend work and production, and the entire industrial chain from raw materials to finished products has been affected. Although my country is currently vigorously developing National Chip, Europe is also one of the important chip producers.
2. Rising raw materials
There is a material called silicon in the manufacture of semiconductors. "Sand" contains silicon elements, and the shortage of sand has increased prices, resulting in price increases in all downstream links of the entire industrial chain.
3. Merchants hoard goods
Some merchants who are more familiar with the industry have stockpiled a large number of spot chips in advance, exacerbating the shortage of chips in the market, and then sold them at a high price.
4. Turmoil in international relations
In recent years, countries have sanctioned each other.
In fact, many high-end chips come from abroad. Due to technical limitations in many countries, some high-performance chips cannot reach the technological level, mainly due to the limitation of precision lithography machines.
Generally, when we say how many nanometers a chip is, it refers to the size of the manufacturing process of the chip.
Under the condition of the same chip size, the higher the transistor density inside the chip, the more precise the process.
It can be simply understood that the smaller the chip size and the greater the transistor density, the more functions the chip can do and the better the performance.
At present, the most powerful is still TSMC, and the one that can reach the mass production level is 5 nanometers.
Last egg time! ! !
Recently, many friends asked me for some MCU learning materials, and then based on my ten years of experience in the industry, I stayed up all night and carefully compiled a "MCU Introduction to Advanced Tutorial + Toolkit", all free to share with everyone! ! !
In addition, I will share with tears my 22 popular open source projects at the bottom of the box, including source code + schematic diagram + PCB + documentation, so that you can quickly advance to become a master!
It is said that a small partner successfully entered the BAT factory by relying on this information, so you must study hard if you save it.
The tutorial package and detailed learning path can be found at the beginning of my article below.
