With these three connection options, the mouse adapts well to different setups—whether used at a desk, on a laptop, or with a console—providing reliable operation across multiple platforms.

EPOMAKER CarbonX’s Online Software

The EPOMAKER CarbonX takes a different path for customization. Instead of using a desktop program, it runs entirely through a browser-based configurator. This system works much like the VIA software popular in the custom keyboard community. The main advantage is convenience—you don’t need to install anything or keep extra software running in the background. For a mouse focused on speed and responsiveness, this setup helps keep the system clean and light. To use it, the mouse needs to be connected through USB, and from there, you can open the Control HUB WEB on the EPOMAKER website to begin adjusting settings.

The layout of the configurator is simple and functional, featuring a dark background with a grid pattern. The top bar includes several tabs: Home, Aiming, Macros, Buttons, and Device Info. It covers all the key functions without feeling cluttered. In the Buttons tab, users can remap controls using a 3D model of the CarbonX with numbered button indicators. The left click is fixed, but other buttons can be assigned to different commands, such as media functions, shortcuts, or custom macros. The debounce setting, which starts at 8ms by default, can be adjusted to fine-tune click behavior. Multiple profiles can also be created and saved, with options to export or import them when switching between setups.

The Aiming section handles sensor and performance adjustments. Up to seven DPI levels can be configured, ranging from 400 to 30,000 DPI, with quick changes available through a slider. The polling rate can be set between 125Hz and 8,000Hz when connected by wire or 2.4GHz wireless, while Bluetooth mode stays at 125Hz. Even when using the higher polling rate, power efficiency remains consistent. Additional settings include lift-off distance (0.7mm, 1mm, or 2mm), ripple control, angle snapping, and motion sync to keep tracking stable. If the CarbonX model includes lighting, basic options for brightness and speed are available here as well.

The Macro Editor section is designed for recording and managing key sequences. Users can record actions, add delays, and decide how often a macro repeats. It’s useful for repetitive tasks in games or applications.

Finally, the Device Info tab shows firmware versions, receiver pairing, and power management settings. All adjustments are stored directly in CarbonX’s onboard memory, so they remain active even after unplugging the mouse.

Overall, the EPOMAKER CarbonX’s web configurator provides a clean and efficient way to customize the mouse without extra software, balancing ease of use with the essential tools needed for performance tuning.

Battery and Charging

The CarbonX uses a 300mAh rechargeable battery, smaller than what some other wireless mice, like the Epomaker Click Mouse, include. Even so, it performs well during everyday use.
