Not only was color CRT display quality problematic, but the devices themselves were bulky, heavy, and sensitive to vibration and shock, which could knock them out of alignment. Although some oscilloscopes were made with traditional color CRTs, the technology was far from ideal.

Above you can see the F&V EverTrue Vari-Color 3×1’s spectral distribution when used at 3200K. While the light does have a nice full spectrum it certainly has a slight push towards green.

The Khadas Edge is further equipped with USB 3.0 and 2.0 host ports and dual 10-pin FPC expansion connectors. The FPC B connector supports the Edge’s onboard 8-bit STM8S003 MCU with programmable EEPROM. It appears that the FPC A connector will support a new Edge IO daughter board, which will enable serial debug, as well as easier GPIO expansion.

The notification drawer feels half-baked as well. The UI is overly simplistic, some elements are misaligned, and the functionality is a little inconsistent. Some ongoing notifications — like the weather notification from the Google app — are not expanded by default, requiring you to tap on them to see them. Other notifications do nothing, they just take up space without offering any information. It’s not a good experience.

The M20 also comes with the Lock Screen Stories feature enabled out of the box. This feature puts a new wallpaper from the internet on the lock screen every time you turn the screen on and allows you to read up on the subject of the current wallpaper. It’s irritating because while you get some stunning wildlife and nature wallpapers, you will also see images of Bollywood actors like Shah Rukh Khan from time to time. Some might like it, but others will just want to turn off the feature as soon as they set up the device.

This board doesn’t seem to be an ideal solution for either an SBC application or a COM application. If I were looking for an SBC, I’d want all I/O features to be readily accessible without having to design a baseboard. That’s the whole purpose of an SBC. And if I were looking for a COM, I’d want first the use of an open standard, which gives me the ability to interchange with other modules from other suppliers, and secondly the freedom to put all I/O connectors wherever I want them, instead of being stuck with the types and positions chosen by the board vendor. Those are the two primary reasons for choosing a COM. It seems that by trying to serve two masters, this board excels at neither.

The wires in those “Dupont” cables aren’t that great, but you can make your own from the housing and crimp pins (which is what I did.) You can also buy “Connector 2.54mm Pitch” similar to those single row PC fan power connector. They come in 2-11 pins. They are available as kits too.

While the Pi wasn’t the first single-board computer, its success has helped spawn many similar devices.

I did something along those lines in college. I used two 5 bit shift registers, and the first bit shifted in must always be a 1, the second bit is the command/data line, and the rest are the 8 parallel pins. the leading 1 bit would trigger an RC circuit at the end of the chain that would trigger the LCD to read the 9 input pins, and then clear the shift registers.
