[Raspberry Pi Pico Review] VII. Raspberry Pi Pico Review Summary [Copy link]

First of all, I would like to thank EE for this Raspberry Pi Pico review event. I learned a lot about Pico hardware and related software during this event. Now I would like to report my review experience in three categories: Pico learning content, advantages and disadvantages.

1. Learning content

1. Learned some ideas of Pico 's hardware circuit design, mainly analyzing DC/DC circuits.

2. Learn the minimum circuit of Pico , how to debug the program, and install related software.

3. Learned how to use Pico 's basic peripherals ( IO, PWM, etc.).

4. Learned some common peripheral driving methods ( LCD1602, DS18B20, FAN , etc.).

5. I learned the basic statements and programming methods of MicroPython . I am a hardware engineer and I usually know a little C programming. This time I feel that MicroPython is not as rigorous and efficient as C. When time control is strict, I feel that it is more convenient to use C.

Second, the advantages of Pico

1. Belief in chips. Raspberry Pi has achieved great success in the field of microcomputers, and the launch of Pico naturally has a large number of followers.

2. In terms of ecology, Pico supports MPY and C. I believe there will be more and more information in the future.

3. In terms of hardware, Raspberry Pi has 8 programmable I/O ( PIO ) state machines for custom peripheral device support.

4. In terms of quality, the quality of Raspberry Pi chips is guaranteed because they are produced by large manufacturers.

5. Easy to download programs, just connect to USB and drag and drop the programs. No debugger required.

6. PCB board is compatible with DIP40 , which is convenient for testing.

3. Disadvantages of Pico

1. The price is still a bit expensive, 30 yuan, while the domestic ESP32 module is only more than 10 yuan, so the price is a flaw.

2. This is a newly launched chip, and the information is less than that of ESP32 , so there are some technical issues that cannot be used as a reference.

3. In terms of hardware, Pico 's IO is 3.3V output, not compatible with 5V , and has no protection. Some peripheral interconnections still have level matching problems. If the IO is connected incorrectly, it is easy to burn out.

4. No wireless function.

Below is a comparison chart between Pico and ESP32 . Please take a look. If you have any opinions about Pico, please leave a comment.

Playing with other things depends on the right opportunity and project. Low-end MCUs can be used, while high-end Raspberry Pis can be used. I feel that Pico is right in the middle of the two. If you need a fast CPU, large RAM, and many PWM channels, you can consider using it.

Very good, very comprehensive summary, thumbs up.

As long as it is made in China, who can win over capitalist things?
