Compare Epomaker Luma40 vs Split70 Differences Side by Side

This comparison is for buyers deciding between two distinct ergonomic approaches from Epomaker. The Luma40 offers a radical 40% ortholinear layout in a compact aluminum body, while the Split70 provides a more conventional 70% layout in a split, gasket-mounted design. The decision is difficult because both support tri-mode connectivity, VIA customization, and hot-swapping, but they cater to fundamentally different priorities in size, typing style, and desk presence.

Pros and Trade-offs

Your primary need dictates the choice. If your priority is a minimalist, travel-friendly keyboard that challenges you with an ortholinear layout, the Luma40 is the compelling option. If you want enhanced ergonomics, a more traditional but split layout with useful features like a knob, and a potentially more refined typing sound, the Split70 is the better investment for a stationary desk setup.

Epomaker Luma40

  • +Ultra-portable 40% ortholinear layout in a compact CNC aluminum case.
  • +Very low front height and low-profile switches may reduce wrist strain.
  • +Includes sound dampening with a switch pad and bottom sponge.
  • +North-facing RGB with light-transmitting PC keycaps for vibrant lighting.
  • +Extremely lightweight at 410 grams.
  • −The 40% layout requires heavy use of layers for numbers, arrows, and punctuation.
  • −Uses a tray mount instead of a gasket mount.
  • −Smaller 1450mAh battery offers shorter rated life (7h RGB on) than the Split70.
  • −Lacks a knob and has fewer immediately accessible keys.

Epomaker Split70

  • +Split ergonomic design with a 7-degree typing angle to reduce arm and shoulder tension.
  • +Includes a programmable knob for media or macro control.
  • +Gasket mount structure with five layers of sound dampening for a premium typing feel.
  • +Larger 3000mAh battery for longer wireless use (11h RGB on).
  • +Uses dye-sublimated PBT keycaps, which are generally more durable than the Luma40's silk-screened PC caps.
  • −Much heavier and larger at 890 grams, making it less portable.
  • −ABS plastic case, compared to the Luma40's aluminum construction.
  • −Split design requires managing two halves and a connecting cable, which may complicate setup.
  • −Some user reviews mention quality control issues with key layout and wireless connectivity.

Which Keyboard Is Better for Your Needs?

The Split70 wins in most productivity-focused categories like Office, Programming, and Content Creation due to its more accessible layout, included knob, and ergonomic split design. The Luma40 is the clear choice for Travel due to its minimal size and weight. For Gaming and Modding, the choice is more nuanced, tied to preference for desk space versus ergonomics, and tray versus gasket mounting.

GamingTie
  • •Both offer a 1000Hz polling rate and 3ms latency in wired mode for responsive input.
  • •Both support N-Key Rollover for simultaneous key presses.
  • •The Luma40's lighter weight and smaller footprint free up desk space for mouse movement, while the Split70's split design may offer more comfortable arm positioning for long sessions.
OfficeEpomaker Split70
  • •The Split70 includes a programmable knob for volume or media control, a useful office feature absent on the Luma40.
  • •Its 70% layout retains dedicated arrow keys and more immediate access to punctuation, reducing reliance on layers compared to the 40% Luma40.
  • •The split ergonomic design is specifically marketed to alleviate arm and shoulder tension during extended typing.
ProgrammingEpomaker Split70
  • •The Split70's larger key count provides more immediate access to symbols and brackets without heavy layer use.
  • •It includes dedicated arrow keys, which are frequently used in code navigation.
  • •Both keyboards support VIA for extensive macro and key remapping, which is highly valuable for coding workflows.
TravelEpomaker Luma40
  • •The Luma40 is significantly lighter at 410g versus the Split70's 890g.
  • •Its dimensions (240x87mm) are far more compact than the Split70's combined footprint.
  • •The vendor description explicitly markets the Luma40 for portability and mobile office use.
ModdingEpomaker Split70
  • •The Split70 uses a gasket mount structure, which is often preferred for its typing feel over the Luma40's tray mount.
  • •It features five detailed sound-dampening layers (Sandwiched Latex, IXPE Switch Pad, PET pad, Bottom Sponge, Bottom Silicone) for acoustic customization.
  • •Both are hot-swappable and support VIA, but the Split70's plate-mounted stabilizers are a more common modding target than the Luma40's stabilizer-free design.
Content CreationEpomaker Split70
  • •The programmable knob on the Split70 can be mapped to timeline scrubbing, brush size, or volume control.
  • •The vendor description for the Luma40 includes a positive review from a content creator praising its aesthetics for camera setups, but the Split70's functional knob and ergonomics may offer more direct workflow benefits.
