NPKC Announces RO75 Compact 75 Percent Keyboard Interest Check

NPKC unveiled details for the RO75 in an interest check published on November 28 2025, presenting a compact 75 percent design aimed at balancing small footprint with full functionality. The listing specified an 81 key layout, aluminum alloy case, a hot swappable printed circuit board, USB C connectivity, Bluetooth and 2.4G wireless options, plus planned QMK support and VIA compatibility. Proposed case colors included Mica Silver, Star Black, Ivory White, Chinese Red and Space Gray. Target battery capacities were listed as 4000 mAh or 8000 mAh on certain SKUs.

The announcement placed technical features front and center, and those details matter for anyone weighing a future buy. Hot swappable PCBs reduce the barrier to trying new switches because soldering is not required. QMK and VIA support mean remapping and macro work will be possible without proprietary lock in. The aluminum alloy case points to a sturdier, heavier build that will affect desk feel and portability, and the dual battery options imply trade offs between runtime and weight.

Community sentiment on the initial thread was recorded as 'Low Interest' with only a few replies at the time of capture. That reaction matters because interest checks exist to guide production choices. The designers indicated responses will be used to refine kitting and layout options, so low engagement can change which colors, battery SKUs or wiring options make it into a group buy or retail release.

Verify whether the final PCB supports south facing or north facing switches, what plate material will be offered, and which wireless mode will include an external dongle or integrated radio. Confirm the exact VIA implementation and whether QMK support will include source code and flashing instructions. Check battery weight and expected runtime for the 4000 mAh and 8000 mAh SKUs to decide if the wireless options meet your use case.

Expect iteration between this interest check and any final product announcement. For now the RO75 is a clear design proposal that highlights modern features, while the community response will steer what version becomes available.
