Welcome to the IT Research Institute column, where Huamei will share practical knowledge about embedded systems, IoT, Java, and more every Thursday. We hope everyone can gain insights and progress further in their professional journey!
Becoming a formal embedded development engineer is a challenging process, from a well-defined development cycle to strict execution and system checks. There are many techniques for developing high-reliability
1. Connection of LED
LED (Light Emitting Diode) is a solid-state semiconductor device that can convert electrical energy into visible light. It directly converts electricity into light. The core of the LED is a semiconductor chip, one end of which is attached to a bracket, one end is the negative electrode, and the other end is connected to the positive electrode of the power supply, encapsulating the entire chip in epoxy resin.Note:
Overclocking the Raspberry Pi 400 is very easy to achieve. In terms of heat dissipation, the Raspberry Pi 400 is designed with a large passive heatsink, which is very useful. There is no need for additional active cooling to meet the heat dissipation needs of overclocking.
Although some users have configured the Raspberry Pi 400 to overclock to 2.2GHz, I believe that 2GHz is more stable.
Overclocking Settings
Here are the steps to configure overclocking on

Introduction
Currently, there is a task requirement for the shopping cart, which involves image recognition and motion control. Therefore, it is necessary to initialize two processes to complete the respective actions. Since motion control requires the results of image recognition, we now need to implement the collaboration between the two processes using Python syntax. This blog combines an actual Python program to achieve process interaction through queues.
Program Analysis
First, let's introduce the libraries we need:
import time
from multiprocessing import Process, Queuefrom multiprocessing import
Recently, I discovered a development board that has not yet been released.
It is the
Banana Pi BPI-M6
The size of the development board is basically the same as that of the Raspberry Pi 4B.
Interestingly, it uses a SoC that is quite rare on development boards, aSynaptics SoC from the USA.
This is the company that makes touch
The Berten team primarily develops high-speed electronic products or provides signal processing solutions for most application needs, especially in extreme environments, through reliable transmission and advanced data processing. The Berten team can often design and develop the best products in the shortest engineering and industrial time. Of course, they offer excellent comprehensive solutions in ultra-high-speed electronic design, software acceleration, HDL programming, data processing, and embedded software. Their technology covers communication,

Emo is a personal companion robot based on Raspberry Pi 4B, combining fashion and innovation. It is not just a robot, but a living existence. Unlike other robots, it has a unique personality and emotions.
According to the standard that size is the original sin, the machine I will share today is indeed a bit confusing. After all, as an ITX host, it is indeed a bit not "mini". Of course, there are actually some similar positioning cases on the market, such as the H200.When I wrote the article, I thought there would be a bunch of ITX purists protesting and denouncing it, but this is really a genuine ITX host, from the chassis to
