Software

On the AKITSU, configuration is possible only through a web driver, which connects through WebHID and therefore will, at least as of now, only work on Chromium-based browsers such as Chrome, Edge, and Opera (desktop). All options are distributed across three pages. The first page has profile management, polling rate adjustment (500 or 1000 Hz, with 2000, 4000, and 8000 Hz being exclusive to wireless operation), lift-off distance adjustment (1/2 mm), and angle snapping (on/off). "Debounce Time" may be adjusted from 0 to 15 ms in increments of 1, and effectively controls click latency. "Sleep Time" defines the idle time required to pass before sleep mode is entered, ranging from 1 to 30 minutes. "MotionSync" synchronizes SPI reads with USB polls, albeit at the cost of up to an entire interval of added motion delay. "Ripple Control" can be enabled to apply smoothing, which lessens jitter at higher CPI steps at the cost of increased motion delay. CPI adjustment is possible for up to five color-coded levels, at a range of 50 to 26,000 in increments of 50, and any non-native values are automatically truncated to native ones. The second page allows button remapping to mouse, keyboard, media, and macro functions. The third page has a macro editor.

All setting changes are saved live to the on-board memory, and the web driver is able to connect to both dongle and mouse.

Battery Life

Arbiter Studio cites up to 60 hours of battery life at 1000 Hz, up to 25 hours at 2000 Hz, up to 20 hours at 4000 Hz, and up to 12 hours at 8000 Hz. Both the web driver and dongle include a battery charge indicator featuring single-digit precision, though it isn't particularly reliable or accurate. For the record, after six hours of mixed usage at 8000, 4000, 2000, and 1000 Hz, the indicator stood at 89%.

Sleep mode is entered after five minutes of inactivity by default, but can be adjusted within the software.

Using the included USB Type-A to Type-C charging cable, I measured the charging speed during the constant current stage, which sits at 0.273 A. The battery has a capacity of 200 mAh (3.7 V) and utilizes a 3-pin JST connector.
