   "description_full": "# 65% MX keyboard PCB (soldered), rev B\n\nA 65% ANSI keyboard main board (68 soldered MX switches) for a gasket-mount case, made by PCBWay as a bare board and hand-assembled, with the USB-C port on a separate Unified Daughterboard and a scripted, strict-grid copper layout.\n\n- Layout: 65% ANSI, 68 keys, 16u x 5u at 19.05 mm pitch. Board 304.8 x 96.75 mm, 2 layers, all parts on the back.\n- Switches: soldered MX switches (5-pin PCB-mount footprint, 3-pin switches fit too). Rev A used Kailh hotswap sockets. 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 straight into each switch pin (no per-key vias); 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: PCBWay, 2 layers, 1.6 mm, green solder mask, white silkscreen, lead-free HASL; bare board, hand-soldered.\n\nEvery part of this board (from the Adom wiki and the board's project library): symbol, footprint and STEP model.
