Vamora75

Vamora75

An 82-key 75 % mechanical keyboard with a 6° typing angle, a tab-gasket mount, hot-swap sockets and an on-board RP2040. Designed by Kevin Le, Sammy DeGraaff and Mohammed-Mehdi Hamdaoui.

Status: revision 1.4, prototype design checked in software, not built yet. ERC, DRC, schematic parity, plate DRC, 14 CAD interference checks and 30 firmware tests all pass (validation/STATUS.md). Build one prototype before a group order and work through the open items in DESIGN_REVIEW.md.

Revision 1.4 adopts all 82 key positions and widths from the supplied Custom layout, including the closer F-row, inward navigation column and End in the top row. USB-C is at the rear-left and the controller is below the spacebar. The USB pair requires fabricator confirmation of 90 ohm differential impedance; see fabrication notes.

Features

• Compact 75 % Windows ANSI layout, 82 keys, matching the full Custom layout
• Hot-swap Kailh sockets for any 3- or 5-pin MX-compatible switch
• PCB-mount screw-in stabilisers on plated, copper-reinforced holes; the plate openings let the stabiliser housings pass through
• Tab-gasket sandwich mount: 8 plate tabs, 16 gaskets at 20 % compression, optional flex-cut plate
• 6° typing angle; two-piece case whose top follows the key clusters, so no plate shows between them; printed in one piece, in 4 pieces for 250 x 210 mm beds, or CNC
• RP2040 on the board (the Raspberry Pi Pico core circuit), USB-C, ESD protection, fuse, BOOT and RESET buttons
• QMK + VIA, or CircuitPython with no compiler
• Black PCB with ENIG gold; "Vamora75" across the PCB front, engraved under the case and in gold on the plate (under the top case); Nam Quốc Sơn Hà and the designers' names on the PCB back
• Generated from source: one command rebuilds the PCB, plate, case, firmware, manufacturing files, 3D models and renders, then re-runs every check

PCBA: parts on the board (197 placements, all on the bottom side)

Getting started

1. Read DESIGN_REVIEW.md: the mount, the stabilisers, what changed, and what to check on the first prototype.
2. Order the PCBA, the plate, the case and the soft parts: Manufacturing/FABRICATION.md.
3. Assemble it: BUILD_GUIDE.md.
4. Flash the firmware: Firmware/README.md.
5. To change the design, edit the parameter files and rebuild: Source/README.md.

Revisions

• 1.4 (2026-11-03): full Custom layout, narrower PCB and case, controller under the spacebar, rear-left USB-C, revised routing, plate, foam, firmware and drawings.
• 1.3 (2026-10-31): USB-C moved to the rear-left corner; only the four arrow keys moved to match the Custom layout relative to Right Shift. Updated PCB, case, plate, firmware layout, manufacturing drawings and validation outputs.
• 1.2 (2026-10-03): top case covers the gaps between key clusters, plate openings and foam windows for PCB-mount stabilisers, plated and reinforced stabiliser holes, black PCB, designers' names on the PCB back, sculpted keycaps, new 3D files and renders.
• 1.1: arrow cluster moved away from the nav column, Joe Scotto's ScottoKicad footprints and models, name-only branding.
• 1.0: on-board RP2040, new matrix and routing, 6° gasket-mount case.
