The PXN CB1 is a dedicated sim racing control button box designed to sit alongside a racing wheel and pedals, giving quick physical access to the dozens of in-game functions (ABS/TC adjustment, pit limiter, headlights, wipers, engine start, DRS, radio) that would otherwise mean reaching for a keyboard mid-race. It packs 30 fully programmable controls into a compact 184 x 144 x 78.5mm housing weighing 540g, including two pushable rotary encoders, six momentary buttons, two latching buttons, a covered "engine start" style toggle, a dedicated ESC button, an ENTER button, a small directional joystick, and several additional toggle switches — enough to cover most sim racing, truck simulator and farming simulator control schemes without needing to remap keyboard shortcuts. RGB backlighting is built in and can be adjusted for colour and brightness directly from the box itself. It connects to a PC over USB-C, runs on 5V/300mA, is fully plug-and-play with no driver installation needed, and mounts either via a desk clamp (for tables up to 70mm thick) or a 100x100mm VESA pattern for rig integration.
