Inside the Tesoro Tizona G2N Elite
As we start to tear down the Tizona G2N, since we had the key puller already to go from looking at the Numpad, we popped a few caps here as well just to verify we have what we should, and indeed we do.
As for the caps used for both the Numpad as well as the keyboard, they are molded in one single color, black, since there is no switch LEDs on this board. They use standard stems to press on the switches, and on top, there are bold and easy-to-read letters laser etched into them, so they won't wear away.
With a fair bit of effort, we got the Tizona down into its major components. Here we have the upper section of the frame lying atop the lower section. The removal of five screws and a bunch of clips will allow the halves to separate, and we can also see the plastic support risers in the lower section that keep the PCB away from the plastic.
While the Tizona G2N is a fully mechanical keyboard, beneath the H-keys, due to the slim profile of the front edge of the keyboard, mechanical switches were just too big. Instead they went with these slightly stiff, rectangular pad style switches.
At the back edge of the PCB, we easily spotted this Genesys Logic GL850G USB 2.0 hub controller for the extra ports at either side of the keyboard. This takes the load away from the MCU, and helps to ensure noiseless, and lossless traffic through those ports.
One of the easy ways to cut manufacturing costs is not to pay a guy to stand there and rub the PCB down with any form of cleaner after the soldering has left its flux residue. On the flip side, it did not cause any issues in our testing.
In one of the few clean areas on the back of the PCB, we located the NXP Semiconductors LCP11U24F ARM Cortex-M0 based MCU that has the option to run in 8-bit or 16-bit, and for what this keyboard has to offer, 8-bit functionality of this processor is more than enough.
With everything back in one piece now, we went ahead and attached the G2N-P to the right side of the G2N, as the number pad would normally be found in any other keyboard layout.
With magnets on both sides of both Tizona components, adding the G2N-P to the left side for left-hand users is as easy as rerouting the Numpad cable, and letting the magnets go to work. Also, keep in mind that we could just use the extension cable, and have this Numpad anywhere it is convenient.
In our last image, we moved the Numpad back to the typical location on the right, and went ahead and powered it up. Since there are no drivers, or LED backlighting, what you see here is what you get. As for lighting, the trio of lock indicators have purple LEDs to match the color scheme.
