Shell & Form
Traditional lightweight mice achieve low weight through honeycomb cutouts — compromising rigidity and feel. The XA25 uses MJF additive manufacturing to print a dense internal orthogrid structure that cannot be replicated by injection molding. The result: full solid surfaces, a slightly textured matte black finish, and a weight no injection-molded mouse can match.
Performance
Custom in-house firmware achieves less than 1 μs overhead above the theoretical minimum for the given hardware at 8000 Hz polling. No off-the-shelf firmware comes close.
PixArt's flagship sensor, paired with a 192 MHz Cortex-M4 MCU and firmware tuned to extract its full capability. Sensor latency is minimized at the firmware level.
1.9 mm diameter, smooth non-braided outer jacket. Fully shielded and compliant with USB 2.0 signal integrity (eye diagram) tests at 480 Mbps. Flexible enough to be nearly unnoticeable in use.
Kailh Sword GM X switches rated 100 million clicks for left and right buttons. TTC Gold Dustproof scroll wheel encoder.
A minimal WebHID-based control panel runs directly in your browser. No drivers, no software installation. Configure polling rate, lift-off distance, and more without bloat.
PCB and cable sub-assemblies are manufactured in China. Final assembly and quality control are performed in the United States by our own hands — every unit inspected and tested before it ships.
About
qsxcv has spent over a decade modding, reverse-engineering, and writing custom firmware for gaming mice. All technical engineering on the XA25 is done entirely in-house: firmware, PCB design, and shell design.
We don't outsource our core work or rebrand someone else's mouse. Every microsecond of latency we've shaved, every gram we've removed, every decision in the XA25 is ours.
