Inside the K68 RGB
The keycaps are made of white plastic, which allows LED light to pass through them. On top of the keys, there is a layer of black paint to limit the light to just what is printed.
Under the keycaps, the view of the Cherry MX Red switches is partially blocked with the translucent rubber membrane. The membrane is high on the switches, leaving just the stems and supporting stems accessible. Doing things this way means that liquids will flow through the keyboard, rather than seeking its way into the switches and the PCB under them.
The frame opens up to expose the ribs supporting the PCB and steel plate, and we can also see the channels the liquid exits the frame through. The top half of the frame hints at the fact that some of the keys are not mechanical, as rubber dome switches back the additional switches along the top edge.
Even though the top edge has rubber dome switches, Corsair made sure to apply the second membrane to cover them, which "locks" under the edge of the first membrane covering the mechanical switches. So, even if you spill something at the top, it will still find its way through the keyboard without damaging it.
Choosing a random spot on the PCB to take a close look at, what sticks out the most is the blue color of the PCB. It stands out because when we look, there is only the slightest hint of the flux used when soldering. The solder points are clean and done right, and we are glad Corsair keeps the quality high, even on parts you will likely never see.
In control of this ship is the NXP Semiconductors LPC11U68JBD100. This is an ARM processor like many we have seen before, and it is also 32-bit, so it has plenty of horsepower to run the features that Corsair built into the K68 RGB.
With everything buttoned up, we plugged in the USB cable to see how the K68 RGB is presented right out of the box. Corsair does not disappoint, as we get the full gamut of RGB colors with them centered about on the L key, spinning in a clockwise direction. What is cool too, is that the lock keys can be color programmed, and you are not stuck with them always being white.
