Following this year's Darwin, RK and other brands launched the axis (chocolate shaft) mechanical keyboard, the domestic peripherals Dalai Penneb also could not hold back, in the recent introduction of a model MT500 low axis (thin shaft) mechanical keyboard. The biggest highlight of this keyboard lies in the aluminum alloy trimming upper cover, which is different from the thin layer stamped on the traditional aluminum alloy upper cover. The upper cover aluminum alloy of MT500 has a certain thickness. With the cooperation of Pyramid's own axis and dwarf keycaps, the MT500's biggest feature has been formed.


One, out of the box

Pennefather MT500 adopts color carton packaging, and the packaged front product picture is clear at a glance.

Pennefather has also devoted a lot of thought to the MT500, and a 300-yuan keyboard also uses the inner and outer box packaging design.

It is already mainstream practice to wrap the foamed film on the keyboard, especially the white keyboard, it is easy to pick up the color on the package.

The Pennefather MT500 has a light-emitting key cap with an aluminum alloy cover and a white cover. In fact, it looks like a sensation in the mechanical keyboard, but it is just plastic and aluminum alloy. MT500 is the plastic under the aluminum alloy, it is worth noting that Yuemi's aluminum alloy is stamped and the thickness is very thin. It does not resemble the “producing for fever” advocated by Xiaomi. I think it was born to be “beautiful”.


Second, product characteristics

The keyboard uses a separate key line design, micro usb interface, common with the conventional Android data line, standard with a 1.8-meter-long glue line.

The back of the keyboard is a light gray plastic bottom case. In the initial state, there are four anti-slip strips to keep the keyboard stable, and the anti-slip strip on the bottom edge is particularly long.

The width of the leg is wider than that of a conventional keyboard. After the leg is opened, there is also a strip to provide stability, and it is easy to fold. It does not require a lot of effort, and the leg rest has a sense of locking and will not fall naturally.

MT500 does not use "chops" for the "low axis" but uses the description of the thin and light axis. The keycaps used also have a low keycap. The height of the keycaps is much higher than that of the conventional original keycaps and OEM heights. The keycap should be a lot lower.

The surface and sides of the aluminum alloy cover have fine frosted grain patterns, texture and fingerprints are not contaminated at the same time, and the edges have been cut and polished. The color value is good, but the disadvantage is that the edges are easily contaminated with fingerprints.

The MT500 is equipped with a set of ABS translucent keycaps. The character is not closed, and it is a good idea for people who prefer the font.

87-key version, removed the keypad area, so that the keyboard is small and easy to carry, not a lot of use of the number keys, use will not be much affected, and the current 87-key gaming keyboard has become mainstream, sales of some brands have exceeded their own full keyboard.

From the side, the height of the entire keycap is on a flat surface, which is low and high. There is a problem on this side. We usually use the mechanical keyboard whether it is the OEM height keycap or the original height keycap, in fact, the entire height side of the keycap. It looks like it is a concave arc with good ergonomics. After using it, I used this MT500 and I felt that the upper two rows of keys were particularly far, but I believe if I used to use it For users of notebooks, switching to a thin and light axis mechanical keyboard with a flat keycap is easy.

In fact, I quite like the design of the key-line separation, but many mechanical keyboards separate for the separation of the key lines, but did not take into account the user experience experience, Pennefax MT500 is not spared, because the outlet position will affect the keyboard flat Next to the laptop, of course, there is no impact on the use of the PC. Therefore, I think that if the interface is replaced with a 90-degree corner, the outlet will be better, or the bottom three-way alignment will be fine.


Third, the axis

The keyway of the thin and light axis is shorter than that of the traditional MX mechanical axis, but it is longer than that of the Darwin's chocolate axis (Kaihua's axis). The key path is between the two, except for the length of the key path and the feel of other. There is not much difference.

It can be seen that Pyramid's thin and light shafts are designed with a cross-axis mandrel. The structure is not different from the traditional MX mechanical axis. The large key position is the same as the common mechanical keyboard. The design of the satellite shaft can also be used. This is Two features make this keyboard capable of using the OEM or the original height of the keycap, but unfortunately, the size of the keyboard's space bar row is not the standard OEM key length so looking for a set of matching keys Cap is hard.

Remove the space big key and found that there is a similar white steel layer on the side of the shaft body. Touching with your hand will find the feel of the steel plate “spraying powder” process, so I once thought it was the steel plate material, in fact, ABS plastic, which is I discovered it through dismantling.

This angle can be seen in fact the white ABS board is not connected with the shaft body, but play a limiting role, ABS board with screw holes, should be connected through the PCB board and the bottom cover, used to fix the upper and lower cover .

This MT500 also has a bright spot that can be switched to Apple's keyboard, through the FN + INS key you can switch WINDOWS / MAC mode.


Fourth, light

MT500 as a white-based keyboard, equipped with a white LED lights, so that the entire keyboard is full of some agitation.

The default lights of the CAPSLOCK and SCROLL LOCK keys are not lit, because the indicator area is missing, so the lights of the two keys will be on after these two keys are activated.

The light is a patch LED on the PCB. After passing through the thin axis of the transparent shaft cover, it shines on the ABS keycap.

V. Dismantling

Similar to the floating keycap keyboard disassembly is generally from the top surface, remove the keycap, you can find the screw holes connected to the upper and lower lid.

The PCB has a metal cover that is attached to the keyboard by a spring, which deflects some static electricity and protects the keyboard.

Originally I mistakenly thought that the white part of the steel plate was originally made of ABS material, and the thickness of the aluminum alloy on the top cover was visible from the figure.

The original interior still had a black steel plate and the shaft was fixed on it.

It took a lot of effort to dismantle the cover, which was difficult due to the fact that the ABS layer had buckles attached to the steel plate.

The snap hole on the steel plate:

PCB board back:

Solder spot diagram:

PCB board is relatively cheap, did not use glass fiber board, can not see where "can save the province"! There is noise! After dismantling, it was found that the desktop dropped a layer of yellow particles from the PCB.


Sixth, summary

Advantages: This aluminum alloy cover feels good, a certain thickness of a little customizable cover.

Disadvantages: Because a piece of PCB board saves a few dollars and becomes noise, it is not worthwhile when everyone uses glass fiber board.

In fact, as a 199 yuan mechanical keyboard, there are aluminum alloy cover, with light, key line separation, good value, plus full discount, really nothing too big spray point, a very affordable domestic machinery office The biggest problem left with the keyboard is the service life.
