Redragon NOVA K709 HE vs UCAL K673 HE: your questions
The primary difference is the layout size. The NOVA K709 HE is a 65% keyboard with 68 keys, sacrificing the function row and navigation cluster for maximum compactness. The UCAL K673 HE is a 75% keyboard with 81 keys, retaining a dedicated function row, arrow keys, and adding a control knob while keeping a relatively short length.
Yes, both the Redragon NOVA K709 HE and UCAL K673 HE feature UltraMag Hall effect magnetic switches. These allow for adjustable actuation points from 0.1mm to 3.4mm and support rapid trigger technology for gaming, as confirmed by the manufacturer's descriptions.
For core gaming performance, they are equivalent. Both keyboards offer an 8000Hz polling rate, rapid trigger technology, and the same Hall effect magnetic switches with adjustable actuation. The choice comes down to personal layout preference, not a performance difference.
According to their respective product listings, the NOVA K709 HE is described as having a 5-layer foam dampening system. The UCAL K673 HE listing specifies a 2-layer noise dampening system. Therefore, the NOVA K709 HE may have a more comprehensive sound dampening setup based on the provided information.
Yes, both keyboards support software-adjustable actuation points for their Hall effect switches. The manufacturer states the actuation can be precision-adjusted in 0.1mm increments between 0.1mm and 3.4mm when rapid trigger is enabled via the software.
The Redragon NOVA K709 HE is more portable. It is a 65% keyboard with a lighter weight of 820 grams, compared to the UCAL K673 HE's 75% layout and heavier 1240-gram weight. The NOVA's smaller form factor is designed to save desk space.
The Redragon NOVA K709 HE comes with POM keycaps, according to the manufacturer's description and product specifications. The listing mentions "smooth full-POM key feel" and lists the keycap material as POM.
The manufacturer states the UCAL K673 HE has multi-platform driver support, including a web-based driver. This allows users on operating systems beyond Windows to access software features through a browser, according to the product description.
The product metadata and descriptions do not explicitly state that either keyboard is hot-swappable. Both listings mention included spare switches and a switch puller, which is common for keyboards with soldered switches that can be replaced with desoldering.
Both keyboards include the keyboard itself, a detachable USB Type-C cable, a keycap and switch puller, spare switches, and a user manual. The NOVA K709 HE listing also specifies a Redragon sticker.
The UCAL K673 HE is generally better suited for programming. Its 75% layout provides a dedicated function row, which is heavily used for IDE debugging and shortcut keys, without requiring a function layer combination. This offers a more efficient workflow for developers.
