1. Micro-USB 2.0 Terminal
The center-mounted port is designed for high-cycle durability. It facilitates both the power intake for the 3260mAh battery and the USB OTG (On-The-Go) functionality, allowing for external storage connection and high-speed PC data transfers.
2. Analog Mic (Voice Input)
The high-sensitivity analog microphone is pre-soldered. It is positioned to align with the bottom-facing mic hole of the Vivo Y81/Y83 frame. This component is solely responsible for your voice quality during calls and audio recordings.
3. RF Signal Hub
The circular gold terminal at the board's edge is the anchor for the Coaxial Antenna Cable. This connection is vital for maintaining 4G VoLTE signal strength. High-quality boards include dedicated signal filtering components to prevent network drops.
