Node75 looks like a budget version of the Air or Halo line. It uses an all-plastic chassis and comes in off white, pink, and black. All versions appear to share a black bottom case, which makes some colorways look a bit mismatched.
Swipe Zone Instead of a Knob
The most noticeable new feature is a touch or swipe zone on the top edge. It works like a virtual knob with volume as the default action, and other functions available through NuPhy IO. This means no QMK or VIA support, which may matter to users who rely on open firmware tools.
Two Profile Options, Probably Not Interchangeable
You can choose low profile or high profile, similar to the Kick 75. Based on the photos, the cases for the two versions look like different thicknesses, so converting between profiles probably will not be possible.
Switch Options
The usual NuPhy lineup is present: red, brown, and blush, offered in Nano (low profile) or Max (high profile) depending on the version you buy.
AirFeet With High Profile for the First Time
AirFeet, previously used only on the Air series, are included here. This is the first time you can place a high profile NuPhy board directly on a MacBook keyboard. The open question is whether high profile switches will block part of the MacBook screen.
Battery and Connectivity
Tri mode support and a claimed 1000 hours of battery life. If real world performance is close, that is a strong number for a mid range board.
Full Size Model Incoming
A Node100 also seems to be in development, with a full size zero key on the numpad.
Early Impression
Node75 appears to target users who want a cheaper Mac friendly board with the general Air typing feel and the new swipe control. The trade offs are the plastic build and the NuPhy IO limitation. Actual value will depend on pricing, firmware stability, and how well the touch zone works in practice.
