ATK has released two new gaming mice in China, the A9 Ultimate Master Edition + and the A9 Air Master Edition +. The launch targets players who prefer mid-to-large hand shapes. Both models share identical external dimensions of 125 by 63.5 by 40 millimeters.
New gaming mice feature Nordic nRF54L SoC and 8kHz polling rate for low latency wireless performance.
The devices utilize the PixArt PAW3955Master sensor for tracking performance. They both run on a Nordic nRF54L system-on-chip and support an 8kHz polling rate in wired and wireless modes. The Ultimate version includes an 800mAh battery, ATK custom optical switches, and weighs approximately 55 grams. The Air variant features a smaller 300mAh battery, ATK Jiguang optical switches, and weighs around 47 grams.

Both models incorporate ATK's 54-series Juesha MAX solution and use a TTC gold wheel encoder for scroll input. The hardware configuration emphasizes low latency and consistent wireless performance across the product line.
ATK positions these peripherals within the Chinese market with a focus on specific ergonomic dimensions. The specification sheet highlights the shared sensor technology while differentiating the two models through battery capacity and overall weight.
