Inside the G613
Shockingly, the keycaps on the G613 are not what we expected to see, at all! We wholeheartedly expected white plastic keys with black paint and white legends applied to them, but we get a set of single-shot caps molded in black, but do have applied legends on them. They keys will never wear out, but the legends can still wear off.
Under the caps are white Romer-G tactile switches. Notice there are no LEDs inside of the switches or around them, as backlighting is not a thing in the G613. We do like the enclosed torsion bars and helper studs, which makes for a more solid feel when pressing the larger keys.
At first glance, you think four screws are holding this together, but in reality, we had to remove thirteen screws to open this puppy up! Inside of the lower frame (at the back), there are ridges to keep the solid feel of the G613, and they offer full support of the PCB to eliminate vibrations. The upper half has the PCB mounted to the frame still, as we have no real need to see the top of the PCB.
Selecting a random spot on the PCB to give it its close-up chance at five minutes of fame, we like what we see! All of the solder points are clean and done well, there is very little remaining of the flux residue, just ghostly rings visible here and there, and we also dig the texture of the PCB.
On a secondary PCB, we found the N52832QFAABO IC, which is the controller of the G613. We believe this is from Nordic Semiconductors. The MCU is an ARM Cortex-M4 which can be either 8-bit or 16-bit, comes with onboard memory, but was selected for the 2.4GHz wireless and Bluetooth 5 capabilities. All the same, even if not a 32-bit option, it has plenty of grunt to handle the feature set and functionality of the G613 without irregularities.
Once reassembled, we plugged in the dongle and powered up the G613. At this time the Caps lock LED, lit a blueish-white color, and the same color is used when the keyboard first comes to life on the battery indicator LED when you tap the wireless button. However, when it comes to Bluetooth and pairing, that same LED will show or blink blue, depending on the stage of connectivity and use.
We went through pairing, found the phone, entered the code, and were set for Bluetooth communications. With that in mind, now you can appreciate the included stand that can hold mobile devices securely and at the proper angle to view it. Due to the offset stand design, it can take on much heavier devices and keep its stability.
