V4 Upgrade Details:
1. Added shielding cover to the Si4732 receiver section to suppress electromagnetic interference; incorporated ESD protection chips at the antenna input for enhanced .
2. Relocated the Hi-Z circuit to the front end of the antenna path and adopted a more stable VCC_RADIO power supply to preserve signal resonance and reduce noise.
3. Added functionality to use wired headphones as an FM antenna (requires use in environments with strong FM signals and sufficiently long headphone cables for optimal performance).
4. Left and right channels have been swapped; amplifier and speaker parameters have been recalibrated to enhance audio quality.
