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…
Two new models, PL-R4 BASIC M2 and PL-R4 RFID, have been added to the PL-R4 series. PL-R4 BASIC M2 The PL-R4 BASIC M2 model is equipped with two M.2 slots for expansion. Both NVMe SSD and LTE communication module, which could not be used together in existing models, can be implemented in a single unit. The nanoSIM slot is located on the front of the main unit, making it easy to insert and remove the SIM card. PL-R4 RFID PL-R4 RFID is an RFID reader model using Zebra’s RE40 UHF RFID chip. x2 port antenna for RFID, 250mW for power saving. Options to add WiFi/Bluetooth and LTE are available. Please…
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.
