'''F21-7D''' is a model of keyboard from Tai-Hao that typically uses [[Tai-Hao APC series]] switches. This model is targeted towards gamers, and features optional high-grip [[Tai-Hao rubber double-shot series|rubber keys]] on the [[WASD]] and [[cursor keys]] (typically orange, but also found in red).

==Description==
F21-7D is derived from [[Tai-Hao F21HQ|model F21HQ]], itself derived from [[Tai-Hao TH-5539-8]] (AKA model APC-8).<ref name="TH-C1" /> The specification differs between OEM customers; features advertised include 18-key rollover (found to be 8KRO during testing) and programmability. The keycaps are black with laser printing.

In most cases, the layout is [[Asian 101]]; however, the AZiO Levetron Clicker has an [[ISO enter]] key, although the layout itself is not [[ISO]] (left shift is full size and the keyboard only has 104 keys).<ref name="CustomPC-KB528U" />

The keyboard is cited (albeit not by Tai-Hao themselves) to have "fully programmable keys" and "10 profiles" but this is not well-documented.<ref name="Rosewill-RK6000" /><ref name="Clicker-F21-7D" />

The [[keyboard controller]] is a glop-top chip-on-board IC on a small PCB, very similar to that used in modern [[membrane keyboard]]s.

==Variants==
Multiple companies have sold this keyboard under their own brands. Tai-Hao also sell the keyboard under their own Clicker brand.

===Wintek WK750===
Unbranded version reportedly sold by Wintek, marked as model WK750, and manufactured in 2011. The switches are indicated as APC BSW 055WH on the box, and appear to be the older teal colour (although some photos are closer to sky blue).
