Board 304.8 x 96.75 mm, 2 layers, all parts on the back.\n- Switches: plain hotswap, Kailh CPG151101S11 sockets for MX-style 3- and 5-pin switches. PCB screw-in stabilizers (Durock V2): Backspace 2u, Enter 2.25u, Left Shift 2.25u, Space 6.25u.\n- Matrix: 5 rows x 15 columns, one 1N4148WS (SOD-323) per key, COL2ROW (cathode toward the row).\n- Controller: STM32F072CBT6 (LQFP-48) under the spacebar, crystal-less USB with CRS, built-in DFU. QMK + VIA/Vial (stm32-dfu bootloader).\n- Pin map (v4): rows PB9 PB6 PB4 PA15 PB3; columns PA0-PA7 PB0 PB1 PB2 PB10 PB11 PB12 PB13. USB D- PA11, D+ PA12, SWDIO PA13, SWCLK PA14.\n- USB: a Unified Daughterboard (UDB-C EZM) carries the USB-C receptacle, CC pull-downs, ESD and over-current protection. The main board has a Molex Pico-EZmate 78171-0004 cable header (J2), 1:1 cable: 1 VBUS, 2 D-, 3 D+, 4 GND.\n- Power: AP2112K-3.3 LDO with 1 uF in/out, 100 nF per VDD and VDDIO2, 4.7 uF bulk, VDDA 1 uF + 10 nF.\n- BOOT0: 10k pull-down + button to 3.3 V. NRST: 100 nF to GND + button to GND. Test pads: 3V3, SWDIO, SWCLK, NRST, GND, VBUS, BOOT0.\n- Copper: rows as one straight line per row on the back under the diodes; columns vertical on the front with 45-degree jogs and the same via spot on every key; the columns reach the chip as two parallel bundles in the gap between rows 3 and 4; rows drop to the chip on the front. GND pour on both layers.\n- Fab: JLCPCB, 2 layers, matte black solder mask, ENIG, bottom-side assembly.\n",+  "brief": "65% ANSI hotswap keyboard PCB (68 keys) for a gasket-mount case: STM32F072 under the spacebar running QMK, USB through a Unified Daughterboard on a Pico-EZmate cable, strict-grid copper, matte black with ENIG.",   "version": "0.2.0",   "visibility": {     "public": true@@ -33,7 +33,7 @@   "discovery_pitch": null,   "metadata": {},   "created_at": "2026-11-09T00:49:05.859Z",-  "updated_at": "2026-11-09T00:49:05.859Z",+  "updated_at": "2026-11-09T22:45:52.373Z",   "component": {     "mpn": "65-KEYBOARD",     "manufacturer": "",
