Inside the Gram Spectrum

Step one, remove keycaps and verify switches. Check. Here we find Kailh branded light blue switches, which are made with a clear top section. With LEDs built into the interior of this switch, it only makes sense to have a clear top to allow the light to pass through them, into the keycaps. We can also see that the torsion bars are exposed in this design, and we also see Tesoro greases them to cut chatter in the keycaps as well.

Each of these 6.2mm keycaps are double-shot caps. This means that an initial casting is made in the translucent white inner caps, and are molded with the numbers, letters, and icons on them. The caps are then molded in black, with the white inserts in place, leaving just the legend exposed at the top, and will not wear anywhere near as fast as painted caps will.

After removing around a dozen or so screws from the top plate of the keyboard, we were able to separate the halves. The lower plastic section is raised in areas to help support the steel plate, where it will not cause issues to the soldering. They also took the extra step to insert padding between the lower section, and the back of the switches. This does two things, it closes the gap between them, which offers isolation, but also is shock absorbent, reducing vibrations.

Picking a random spot on the bright red PCB, we see a fine attention to detail has been paid to the soldering and flux removal. There is a bit of sticker residue near the bottom, but it should not affect the electronic signaling these solder points give.

The 32-bit ARM Cortex processor for the Gram Spectrum is made by NXP. We find the LPC11U35F in control of this keyboard, and with its specifications, it is enough to deliver everything we have spoken on about the capabilities of this design.

When we first powered the keyboard, we set a few of the Locks as activated, showing their blue LEDs, but at the time of powering it up, you were given the Spectrum effect for a few seconds upon loading. After loading the device, it quickly reset to this solid blue coloring we see in this image.
