Nowadays, various Pi boards are emerging, such as Raspberry Pi, Orange Pi, and the previously shared Remi Pi. What other Pi boards do you know of?
Today, I bring you another Pi board – Mifans Pi T527, which is the first industrial development board launched by Mil Electronics, featuring edge computing with high-performance Allwinner T527.
Since its market launch, it has attracted widespread attention from customers due to its ease of use, high reliability, high performance, low threshold, high integration, open-source design, support for secondary development, and rich software resources. This time, the Mil-Allwinner T527 development board has released the TINA5.0 (Linux 5.15) system for industrial applications. To thank everyone for their support, we are offering a limited-time 30% discount on the Mifans Pi T527, with only 200 sets available, and the price will revert to the original once sold out.
The TINA5.0 (Linux 5.15) system of Mifans Pi T527 is an image built based on buildroot with a QT5.12 interface, including complete hardware drivers, commonly used system tools, debugging tools, etc., containing GUI runtime libraries and HMI interfaces. It supports application development using Shell, C/C++, QML, and Python.

1.MEasy HMI 2.0 Framework
MEasy HMI 2.0 is a human-machine interface framework developed by Shenzhen Mil Technology Co., Ltd., based on QT5. The project uses a hybrid programming of QML and C++, where QML is used to efficiently and conveniently build the UI, while C++ is used to implement business logic and complex algorithms. Depending on the type of application, we divide the entire UI into five main categories: multimedia, smart home appliances, health care, public services, and systems. Each category contains different subclasses, and we implement corresponding applications for each subclass, as shown in Figure 1.

cyclictest -t4 -p 80 -i 10000 -l 10000
Test results are as follows:
stress-ng --sock 36 --taskset 0,1,2,3,4,5,6,7 --timeout 120h & stress-ng -c 36 --taskset 0,1,2,3,4,5,6,7 --timeout 120h &
cyclictest -t4 -p 80 -i 10000 -l 10000
Test results are as follows:
cyclictest -t20 -p 80 -i 10000 -l 10000
