By chance, I stumbled upon a tutorial for flashing the AX3000T on a small video site and decided to give it a try. I purchased the device and followed the tutorial to flash uboot, testing various firmware. However, the AX3000T with its 256MB of RAM was too limited, and running the OpenClash kernel often resulted in crashes, rendering it completely unusable. Therefore, I learned to customize and compile my own version, only including necessary plugins. I tested the source codes

Edge network device applications must acquire, process, and understand data points at high sampling rates.MCU (Microcontroller) is a key component of many embedded systems, increasingly responsible for capturing, processing, and managing the data flowing through them. This process begins at the local device, and manufacturers are seeking innovative opportunities to understand and monetize every bit of data they can collect.

MCU real-time data acquisition and management face several challenges. To overcome these obstacles, we designed ITTIA DB IoT, which executes

Recently, I mentioned that mini PCs are emerging one after another, and a new product from the brand Minisforum has appeared. This Mini PC uses a niche CPU, the R5-5625U, which is equivalent to a semi-system, priced at 1988 Yuan. Let’s take a look.

First, let’s talk about the R5-5625U. It belongs to the new U series released this year, alongside the 6600U. The
