In this review, we will explore the Radxa 03w. This is a single-board computer with a zero form factor, equipped with a quad-core processor, and various options for RAM and internal storage. Let's dive in and take a closer look!
Here, we have the Radxa 03w with 2 GB of RAM and onboard 16 GB EMMC flash storage. I got it from Allnet for $33, and the models vary from the 1 GB variant without EMMC and GPIO header priced at $19 to the 4 GB variant priced at $68, just to add to the confusion.
If you're a bit confused because RS also sells a board called Rock Zero 3w, don't worry. I'll discuss the differences later.
Let's unpack this new single-board computer. Easily remove the wrapping, and inside, we'll find an anti-static bag. No special tools are needed; we can open it easily.
And there it is, the Radxa 03w, an intriguing single-board computer! Don't worry; we'll look deeper. At the heart of this board, we find the Rockchip RK3566 system with a quad-core ARM Cortex-A55 running up to 1.6 GHz and Mali-G52EE GPU. We also have a low-power DDR4 RAM of 2 GB.
Looking at the front, we find a micro HDMI connector supporting 1080p up to 60 frames per second. There's also a USB-C connector offering USB 3.0 host connectivity. We even have a second USB-C connector that can be used to power the board, in addition to providing USB 2.0 data transfer for emmc programming.
Switching to the back, we find a 40-pin color-coded GPIO header. However, it's essential to note that not all Radxa 03w models come with a populated header.
At the bottom, we find emmc, an internal 16 GB flash storage, and a micro SD card slot. There's also a CSI, a serial camera interface connector, allowing us to connect a camera to the board.
How about the performance of this board? I have tested some features to give you an idea. YouTube video playback runs reasonably well, although with a few dropped frames. This is not bad considering it's a zero form factor single-board computer.
For speed, I tested the micro SD card and emmc. The micro SD card speed reached 64 megabytes per second, while the emmc speed reached 161 megabytes per second. The performance of this emmc flash storage is much better, and in the future, we hope to run the operating system from it.
That's a brief overview of the Radxa 03w, a promising single-board computer. Although there are still some challenges in installing the operating system on emmc storage, we remain hopeful for solutions in the future.
