Raspberry Pi is a small computer the size of a credit card, which you can connect to a TV, monitor, keyboard, mouse, and other devices.

Raspberry Pi can replace various everyday desktop computer uses, including word processing, spreadsheets, media centers, and even gaming. Additionally, Raspberry Pi can play high-definition videos up to 4K.

We hope to promote Raspberry Pi to young computer enthusiasts around the world to cultivate interest and skills in computer programming.

Facing various generations of Raspberry Pi products, DFRobot application engineer Zheng Junfeng will introduce various specialized interface expansion boards and function expansion boards to address urgent needs during usage.

When it comes to Raspberry Pi development boards, most players are familiar with its classic series. However, for some lightweight applications, excessive resources can indeed be a waste. In this case, the emergence of Raspberry Pi Pico undoubtedly brings a suitable compromise.

What advantages does Pico have compared to traditional Raspberry Pi series? Which is more suitable for your current design, Pico’s main chip RP2040 or ESP32? What languages can support development? Are there any useful expansion boards that can match it?

Bilibili famous UP owner “Engineering guy Teacher Sun” will guide everyone to thoroughly understand this lightweight Raspberry Pi development board.

For deep players, having a more compact size and removing unnecessary interfaces is undoubtedly a more suitable choice for high-end players and even some small batch customization markets.

The core board CM4 undoubtedly fills this demand, maintaining the hardware performance of Pi 4 while making the PCB size more mini. CM4 has no interfaces, and developers can add interfaces according to their project needs. Many makers have turned to this more playful small product.

Continue to follow Teacher Li Weibin to create a small desktop reminder using an E-Ink screen and Raspberry Pi 4B, making daily data clear during the fluctuating pandemic.

Using HuskyLens for image recognition with Raspberry Pi, let’s explore some of the popular artificial intelligence visual recognition directions and store the corresponding results in a database.

As an easy-to-use artificial intelligence visual sensor, this product has built-in six functions, including face recognition, object tracking, object recognition, line tracking, color recognition, and label (QR code) recognition. It can also be used with Raspberry Pi (or other main control boards) for interesting human-computer interaction projects.

Let’s learn together with Teacher Li Weibin～

The rainy season is approaching, and many places across the country will experience a period of hot and humid weather again. As an electronics enthusiast, do you want to have a homemade temperature and humidity recorder to digitize the data?

This type of temperature and humidity recorder will be very convenient for monitoring changes in temperature and humidity at home and can also serve as a basic module for advanced gameplay, linking with smart devices at home to achieve interesting and practical functions such as intelligent dehumidification of air conditioning.

The hardware used for the project is not complicated; today’s selected Raspberry Pi series product is Raspberry Pi Zero 2W. Also selected are a mobile power expansion board, IO expansion board, temperature and humidity sensor, and batteries.

During the implementation of various projects, another issue we need to pay attention to is the heat generation of the processor and board. This issue with Raspberry Pi is often criticized and can cause some troubles.

In response to this issue, today in the final lesson of this series, we will let the data speak and create a cooling data storage solution to collect and record CPU temperature over a long period, then analyze and display it to observe the CPU temperature and system pressure status. On this basis, this lesson will also introduce several commonly used heatsinks and popular cooling cases, so that everyone’s projects have no temperature pressure concerns.
