Inside the PRO

All of the keycaps use a 4-pin system to lock into the outer edges of the Romer-G switches, but for the longer caps, secondary support uses a typical Cherry MX pin. Each cap is made of an opaque shot of plastic into the mold, and once completed, the caps are coated in black and laser etched.

Each of the Romer-G switches is open in the middle, which allows for the LED to be placed there, and they do not leak a bit of LED light out anywhere but through the legends on top of the caps. The torsion bars are internally housed, and in tiny letters, we found the Omron name on the angled section of the switch covers.

The feet all have to come off, and a hole has to be poked in the sticker under the keyboard to allow the frame to be opened. In the top section, we see captured buttons for the Game lockout key and the LED switch, and there is a clear section to the right backing the G logo. The lower frame component uses one rib across the span in conjunction with raised cylindrical supports to keep the steel plate from flexing and vibrating.

The PCB in the PRO is green, and there is no flux residue left on it. All of the solder points are clean, and we find no lack of quality control when it came to making this keyboard.

This ultra-low power MCU we find in the PRO is the STM32L100R8T6. This is an ARM Cortex M3 processor which has a frequency of 32MHz and a maximum of 128 Kb of onboard storage.

Before we button things back up with the PRO, we also flipped over the assembly to locate what switches back the Game Mode and LED buttons. Here we located them, but all we can say is they are black pad style switches with no name or identification on visible on them.

Fully reassembled, we plugged the PRO into the PC and are greeted with a default pattern. Without messing about in software, the PRO's LEDs will be displayed in the full spectrum of colors as they scroll across the board from left to right. The logo will change color but is not in sync with the rest of the keyboard, but the lock indicator LEDs are always that light blue.
