The Leopold FC660C is a 66-key Electrostatic Capacitive Mini Keyboard with the Topre switch. The switches are plate mounted in this keyboard, similar to the Topre Realforce line of keyboards. This keyboard is unusual in that it is slightly larger than a normal 60% keyboard, and has dedicated arrow keys and an insert and delete key on the right. FN+arrow-keys perform home, end, page up, and page down, however this is not printed on the front of the keys. FN+Q inverts the FN layer on Escape, making it into the `~ key by default. When this is toggled, a red LED on the INS key lights up. There are 4 dip switches to adjust the layout. Out of the package, the Leopold FC660C comes with the keyboard, a gold plated USB cable, and an extra 1.5 ctrl key and 1.25 caps lock keycaps to swap positions. On the back there are standoff feet available, and unlike the Happy Hacking Keyboard, the FC660C’s feet are rubberized for better grip on the desk. Also unlike the HHKB, the FC660C only has 1 height option and is somewhat steep for normal standards; however the incline feels roughly the same as the HHKB. The switches come in 45g uniform weighting. At the front right the equation for computing capacitance is printed on the case. The white variant appears to be slightly off-white compared to typical Topre switch boards such as the HHKB.
The FC660C features high-quality thick (up tp 1.5 mm) PBT keycaps. Note that:
- All FC660C variants come with PBT keycaps and never with ABS or any other plastics, except for the spacebar which is always ABS, similar with most other current Topre switch keyboards, such as the Happy Hacking Keyboard and the Topre Realforce line.
- While all FC660C variants' keycaps are PBT, the legends print method may be different, for example, the Hangul (Korean/US) black version is using the lasered PBT keycaps while two other variants in the gallery below have the dye-sublimated PBTs. Keyboards using the dye-sublimation method are clearly and prominently marked as such on multiple sides of its packaging. Consequently, the absence of the "dye-sublimation" wording on the box indicates the lasered PBT legends. The bottom key caps are 1.25u 1.25u 1.25u 6u 1.25u 1.25u 1.25u.
Push for Quality
The FC660C was designed by Leopold, manufactured in China - most likely by Varmilo, and inspected in Japan (likely by Topre). From the start of the FC660C project, it has been very important to Leopold to really impress Topre with the quality of this product.[Citation needed] No corners were cut, no expense spared to build a keyboard that's on par with Topre keyboard products, and in many ways that was successfully achieved. From the outside, the FC660C with Topre switches and high-quality PBT keycaps looks like a nice alternative to the HHKB Pro keyboard, especially for many users who prefer a dedicated arrow/cursor cluster. On the inside there are no cost-cutting components – all of the internal components were built by Japanese manufacturers (Shirai, Taiyo Yuden, Toshiba, ROHM, KOA, NEC, TDK, Hirose Electric, Murata, Seiko, Hitachi HWCS, Fujitsu, etc.) in addition to a few coming from the US manufacturers (Texas Instruments and Analog Devices).
