Switch Type: Gateron Low-profile Mechanical (KS-33) Layout: ANSI 75% Number of Keys: 84 Hot-swappable Support: Yes N-key Rollover Support: Yes Backlight: RGB-LED Backlight Modes: 40 Compatible System:macOS/Windows/Linux/Android/iOS Angle:3.5°/6.5°/8.5° Operating Environment: -10 to 50℃ MCU: STM32F072 RF: NRF52810 As much as we pride ourselves in building innovations and our own ideas into our products, we will have to make an exception for firmwares: starting with Air75 V2, all Airs will be shipped with QMK/VIA. We believe with the full realization of our hardwares' potential under the new firmware, its open source code, the endless key remapping, light customization and other creative possibilities VIA offers our users, the fun has truly started! Mode: 2.4GHz, Bluetooth 5.1 or Wired (USB-C) 2.4GHz Polling Rate: 1000Hz Bluetooth 5.1 Polling Rate: 125Hz Wired Polling Rate: 1000Hz Battery Capacity: 4000mAh Size: 316.4 mm x 132.5 mm x 13.5 mm Weight: 598 grams Frame: Aluminum Bottom Case: ABS Keycap: Double-shot PBT A 1000Hz polling rate may be eye-catching, yet actual latency depends on factors including MCU’s matrix scan rate, processing and debounce time, the wireless cache size etc. Never content with half measures, we support Nordic's NRF52810 SoC with STM32F072 MCU's high performance, and use an elaborate testing procedure to ensure minimized total trip delay.
