TT ESPORTS POSEIDON Z RGB
The Tt eSPORTS Poseidon Z RGB is a compact mechanical keyboard with a simple matte black, plastic build. The keys are mounted onto a steel plate for extra stability, and the plate itself is finished in a reflective, glittery coating that helps reflect the LED lighting. The keyboard doesn't have any dedicated media or macro keys, so the Function keys double up as media controls, while the Insert row is used to store macros (and to activate N-key rollover). There's also an on/off arrow switch in the top-right corner that activates gaming mode, which makes the macro keys usable, and also turns the Windows key into another control key.
Under the keys, the Poseidon Z RGB uses Kailh mechanical switches, the Chinese clones of German Cherry MX switches. Unlike the transparent switch housing used on Cherry's RGB switches, the Kailh switch has the LED built into the top of the switch. This results in the lighting not being quite as bright or uniform as Cherry switches (we also saw this with the Armaggeddon MKA-11R). According to Kailh, their switches are rated for 50 million key strokes, which is exactly the same as Cherry switches, but it remains to be seen if they'll actually hold up for that long. The Poseidon Z RGB is available in either Blue or Brown switches, both of which are tactile. Unfortunately, there's no option for the linear and very popular Red switch, which is unusual for a gaming keyboard.
Thermaltake uses an NXP LPC11U3 micro controller inside the Poseidon Z RGB, which combines a 32-bit ARM Cortex M0 core with a 16-bit LED controller. The keyboard requires installation of Tt eSPORTS' Poseidon Z RGB software to control the lights, as without it, it will just shine a monotonous red color. Once installed, lighting is easy to configure and the software gives you full control over the color of each key, as well as a number of animations and effects. The backlighting isn't quite as bright as others we've seen, but it's sufficient. With the software installed, you can also record macros on-the-fly by pressing Fn + F9. Overall, while the Poseidon Z RGB doesn't offer a whole lot in terms of features, it gets the job done, and it's also much cheaper than our other keyboards.
A switch in the top-right corner lets you activate gaming mode.
