C4 Capacitor Function Overview
Thought for 5 sec
I’ll set this up as a module-based prototype layout so you can compare the physical size, but since you only have comment access on this project I may need to create or use one of your editable projects instead of modifying this one.
Thought for 14 sec
I started the module-based prototype plan, but I can’t continue executing because there are no available ACUs right now.
What’s defined so far:
- Module-first architecture: RK3036 Miracast module + HDMI/S-Video converter module + ESP32-WROOM-32E audio/Bluetooth.
- Minimal 20-pin FFC to projector: S-Video GND/Y/C plus 68 kΩ accessory-detect pair.
- Independent battery power: 1-cell LiPo via 1.5 mm 2-pin JST, USB-C charging, MAX17043 fuel gauge, boost to system rail.
- Target size estimate: roughly 60 × 45 mm to 80 × 55 mm, with ~70 × 50 mm as a realistic first-pass board.
What remains:
- Create or fork an editable project, since this project is comment-only.
- Add the module-based schematic blocks.
- Place modules/connectors/regulators into a preliminary PCB layout.
- Generate a 3D-viewable board size comparison.
