Rosewill RK-9000V2 RGB Mechanical Gaming Keyboard Review

Inside the RK-9000V2 RGB




Removing five keycaps to expose what is under them we find a few things worthy of noting. First of all the steel plate is painted white to help with LED brightness and reflectivity. All of the switches have clear bodies and brown tactile stems made by Cherry MX. The last thing to note is that the torsions bars are exposed, so take heed when it comes to removing the longer keycaps.





All of the keycaps are shot in an opaque white plastic and are then painted over with textured paint application. Once that has been down, the legends are all laser etched through the black coating, and easily allows light to pass through each cap.




Since the PCB is dual layer, and it gets mounted to the steel plate inside, there is not so much of a need for ribs in the lower section of the frame to help support it. The top section requires the removal of three screws and the release of many tabs around the edge before it can be removed from the lower section.




Getting up close and personal with the bottom of the PCB shows us that everything is as clean as can be. The solder points are small, and even on all of the pins, each switch has its individual LED visible, and there are no signs of residue to be found anywhere on this PCB.




With so many built-in features and things that the RK-9000V2 makes available to do with it, the use of this Holtek HT32F1655 chip is appreciated. This is a 32-bit ARM Cortex-M3 processor with a 72MHz core clock and is also where the profiles and Macros are stored. However, there is no mention of how much of the 256KB of space is left to fill by the user.




With our RK-9000V2 RGB back together, we powered it up and found that a wave of color is running from left to right, across the keyboard by default, but once adjusted we were not able to get back. Of course, we took the time to play with the various modes, and all of them work as intended, and gives quite a bit of option when it comes to the lighting you can get from this keyboard.




We found this mode to be our second favorite, which is the wave mode. This mode offers a line across each row of keys to be illuminated the same color, as they evolve through the RGB scale, moving from the top to the bottom. There are many other ways the keys will react to your input, or run in the background while you type, but most of them are not easy to get in images.
