OSD redesign based on Jason Young's (RPi) proven topology:
- Replace GS8052 dual op-amp with dedicated ICs: TLV3201 comparator,
SN74LVC1G3157 SPDT mux, TLV9061 non-inverting buffer, SDM02U30LP3
Schottky for DC restore
- Add chroma filter (680R+470pF), AC coupling (1uF), resistor divider
pixel level (12k/3.9k/1.4k), gain-2 buffer (470R/470R)
- Fix C66 footprint 0201->0402 for 1uF cap
- Assign correct LCSC part numbers for all 13 OSD passives
Library fixes:
- Add new footprints: X2SON-4, X2SON-6, X3-DFN0603, SC-70-6,
SOD-523, SOT-23-5, MouseBite for local OSD components
- Add matching 3D models (step+wrl) for all new footprints
- Fix 8 footprints with broken 3D model paths in lib.pretty
(/.3dshapes/ -> ${KIPRJMOD}/lib.3dshapes/, remove double hardware/)
- Fix 5 broken 3D model paths in PCB file
- Add symbols for TLV3201, SN74LVC1G3157, TLV9061, SDM02U30LP3
- Add datasheets/ and image (1).png to .gitignore
