Sentraq started out making small, 3D-printed keychains and, not long after, began designing and manufacturing its own mechanical keyboard kits and accessories. A follow-up to the popular S60-X keyboard kit, this offers an affordable, functional introduction to custom numpads. Finally—a 4x5 numpad that carries RGB underglow! The kit comes with all the components you need to get started, including a new, designed-from-scratch printed circuit board that’s fully programmable via QMK firmware. Complete with an aluminum case and plate, it features RGB underglow with an acrylic bottom for lighting effects that pop off your desktop. All that’s left is to do is solder in the switches.
