Inside the Sentey Crimson Pro
The provided key puller works well to pull these painted caps off of the keys. However, looking closely, we see the puller scratches the matte finish on the frame around them though. So only pull the key caps if absolutely necessary.
There are Cherry MX black switches under all of the caps on this keyboard's layout. Each switch is also individually LED backlit, and the LEDs are only red in color.
Getting the frame apart was pretty simple after removing all of the screws. We see that the bottom of the tray has supports to keep the PCB from flexing, and the top section uses thick plastic to give the thin sections some strength.
Picking a random spot on the PCB to look at the clean up job after the soldering was finished, we find that most of the residue has been cleaned up, with only minimal spots here and there of leftover flux.
Sentey has employed the services of this 8-bit Freescale MCU. The MC9S08JM16 is where all the traffic of signals flows in and out of the keyboard, and it is also where the 128kb of onboard storage is housed.
To control the traffic of the additional two USB 2.0 ports on the back of the Crimson Pro, we find this Genesys GL850G hub controller. It also has an 8-bit MCU to handle the traffic, and we found it to work well with our testing of those ports.
Just to sort of show how the orange key caps play against the rest of the black keyboard, we installed them onto the arrow keys; they do look pretty slick.
With everything reassembled, we went ahead and powered up the Crimson Pro. Now we have all of the keys illuminated as brightly as they will go, and we also have the lock keys pushed to show off the boxes at the top right edge of this keyboard.
