We verified the operation of a SIM called “MEEQ SIM”, a communication service for IoT available from 143 JPY/month (tax included), with PL-R4.
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…
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…
We have released a video demonstration of equipment failure indication detection using the industrial Raspberry Pi PL-R4 and acceleration sensor. This time, it is a wireless configuration assuming a large number of equipment or a long distance.
The biggest advantage of Raspberry Pi Connect is that screen sharing can be done in a very simple procedure. You can access your Raspberry Pi OS desktop at home not only locally, but also via mobile communication such as a smartphone.
We tested the official Raspberry Pi AI camera module on an industrial Raspi (with CM5) connected to the AI accelerator Hailo.
The current OS allows the Raspberry Pi Wi-Fi to be converted to an access point without using other applications with NetworkManage.
For industrial raspi, the procedure is a bit more complicated, but it is convenient to backup with the dd command and compress with PiShrink to shorten the write time. For general Pi 4 and Pi 5, the dd command is used to backup the entire system as an image file, as in this case. Please refer to the following.
Have you ever wished you could plug a SIM card directly into your Raspberry Pi (Raspberry Pi)?On commercially available Raspberry Pi, a 4G (LTE) module can be realized with an extended HAT or with a USB-connected communication modem. On the other hand, did you know that there are Raspberry Pi products specialized for industrial applications that allow SIM cards to be inserted without modification? An industrial Raspberry Pi, housed in a rugged enclosure, can adapt to harsh environments such as factories. If possible, you want to keep both the SIM card and the 4G (LTE) module in it. PiLink offers a model that supports 4G (LTE) communication, so we borrowed…
We will show you how to mount an NVMe-connected SSD drive in the industrial Raspi “PL-R4” and treat it as a boot drive.
