XA25 Batch 1 is sold out. Thank you all for the support!

We're opening a batch 2 waitlist on our website xbabtech.com

The waitlist has a limit of 1000 emails. All 1000 emails will get a 24 hour exclusive period with a guaranteed chance to order in batch 2.

first XA25 world record!

The XA25 and @tekkusai's Kunai will be the first mouse to feature SensorLock, our jointly developed technology that synchronizes sensor frame capture with USB polls to eliminate micro-stutters and minimize latency, inside the mouse.

Here's our full blog article: xbabtech.com/blog/sensorloc…

In this article, we also go in-depth on a long-standing mystery: what Motion Sync actually does. tldr: It's far more than synchronizing SPI, which many have been led to believe. Motion Sync is an algorithm that buffers and smears out data temporally, in order to eliminate micro-stutters at the cost of a polling interval's worth of extra latency. Source: PixArt's patent US11385069B2.

Unlike Motion Sync, Frame Sync removes micro-stutters without a latency penalty. But it requires sensor hardware that's currently exclusive to Razer. SensorLock is our technique to do the same, on sensors such as the PAW3950 and PAW3955.

In our video in October, we shared preliminary numbers on how SensorLock compares to Frame Sync in latency. Here are the latest numbers we've measured for the time between the sensor capturing a frame and the corresponding USB poll+response.

Viper V4 Pro, Frame Sync (wireless 8k): 285 μs
Kunai, SensorLock (wireless 8k): 80 μs
Viper V4 Pro, Frame Sync (wired 8k): 205 μs
XA25, SensorLock (wired 8k): 37 μs

Physical latency measurements, such as @Tw1tterIsGood's, would be about 62.5 μs higher than these values.

On the XA25, SensorLock is still being tested and optimized. Our first priority is to produce and ship the remaining ~200 units to our customers by the end of the month. The SensorLock firmware update will be finalized soon after.

Update on XA25 batch 1 production: over the last two weeks, we've assembled and shipped about 260 XA25's (up to order numbers around 1250s). We expect to complete the remainder in the next two weeks or so.

On our Discord, we provide bi-weekly updates of our progress.

XA25 orders begin shipping today.
