Inside the PRO X
Once we removed the keycaps, the appearance of the muted legends makes sense. Rather than milky white plastic, Logitech has opted to use clear plastic for the molds and then applies a matte black coating to them. It certainly helps with the lighting, but with the LEDs off, and limited light in the room, the legends get challenging to make out.
On the PRO X keyboard we have, we found Kailh blue switches under every keycap, but the game lockout and LED control buttons are pas-style switches. Each switch has a transparent body with an internal RGB LED, and we also see helper studs on top of the torsion bars on the larger keys.
Using the same tool we removed the keycaps with, we grabbed hold of the switch, and with some force required, it eventually lets go of the two pins for switch removal. You will also need the tool to reattach the switch, as the lock tabs need to be pressed for the switch to be inserted into the PCB.
If for some reason, you buy the PRO X keyboard, and you find the need to change switches, or maybe you plan to keep the keyboard forever and want a set to backup all of the switches you already use, Logitech has a solution. Sold in ninety-two switch kits, you can buy brown, red, and blue switch replacements. Also included in that $49.99 price per set, is another keycap and switch puller tool, just like the one we found in the PRO X keyboard box.
All of the feet have to be removed to get this keyboard apart, and there is one also hiding under the product sticker. Once they are all removed, we can see the lower section of the frame and measures taken to keep it from flexing of vibrating. The top portion contains the top and sides of the frame, which has the PCB attached to it with screws.
Unlike with the conventional mechanical switches, we do not see the pair of pins getting soldered directly to the PCB, nor do we see where the LEDs are connected. Instead, we find rows of black plastic bases applied to it, clean and precise in their application. It is also possible to make out the pins on the switches, and they are gripped with a pair of tabs, which are soldered to the PCB.
In control of everything, the PRO X can and will do, is this MCU. It is a 32-bit ARM Cortex-M3 processor that goes by the model STM32L100R8T6A, built by ST Microelectronics. The chip has plenty of grunt to deliver what is expected from this keyboard!
The last thing to do, once we had the PRO X back in one piece, was to power it up. In doing so, we are greeted with more glow from the switches, through the clear bodied keycaps. Right out of the box, we have a rainbow effect traveling from left to right across the keys, and we also see the Logitech G logo and lock indicators with their pale blue backlighting. The game lockout and RGB LED switch will change colors, matching whatever effect is in use.
