Not many people can handle programming at will. This is especially true if it is not part of their job. However, it is no longer necessary to know how to program at all. I am also one of those people who cannot write programming code from a completely blank sheet of paper. So far, there was nothing I could do about it, but with ChatGPT, I can now explore mistakes and questions in my code. ChatGPT, which has been available to everyone since 2022, has evolved considerably since its introduction. The ability to ask questions is important because it is used in the form of asking questions and receiving answers,…

7 OSes that can be utilized with the Raspberry Pi CM4

PiLinkTutorial

The factory image of PiLink’s industrial Raspberry Pi PL-R4 with the CM4 installed has the Raspberry Pi OS installed; Ubuntu can also be run on models with 4GB RAM or more. There are many other operating systems that can be run on the Raspberry Pi, so we will introduce the 7 operating systems that can be installed* on the Raspberry Pi CM4.

Benchmark test comparison of the new Compute Module 5 with the previous CM4

PiLinkTechnical

The new Compute Module 5 (“CM5”), like the commercially available Raspberry Pi 5, has a significant performance boost.Therefore, we tried benchmark tests with Compute Module 4 (“CM4”) and CM5.We used Geenbench and PiBenchmarks. The PL-R4 and PL-R5M were used for the trial.The operating system for the “PL-R4” with CM4 is bullseye and the “PL-R5M” with CM5 is bookworm.Each is activated by eMMC. Geekbench Geekbench, the famous benchmark test, can be run on the Raspberry Pi. However, only the preview version, which is treated as a beta version, is supported. This is because the CPU is an Arm. Geekbench preview version: https://www.geekbench.com/preview/ For Linux, I found that it is compatible with…

USB-type Wi-Fi adapter (dongle) LM808 and LM842 settings and why you dare to choose them

PiLinkTechnical

In addition to the built-in Wi-Fi function, computers can communicate wirelessly via a Wi-Fi adapter (also known as a dongle) that connects via USB.In this issue, we will introduce an example of using a non-wireless model “PL-R4” with a USB-type Wi-Fi adapter attached. The PL-R4 series of industrial-use Raspis includes a model that incorporates the Raspberry Pi Compute Module 4 with Wi-Fi as usual, as well as a model that is not wireless-compatible. Non-wireless models are also in demand. This is because there are some industrial sites where Wi-Fi is not or cannot be used depending on the application. The PL-R4 is wired as standard, and Wi-Fi is an optional…
