The Realme 5 Pro (RMX1971) Charging Flex, also known as the Sub-PCB or Charging Dock Assembly, is a vital internal component that manages the power entry and signal distribution for the device. Because the Realme 5 Pro supports VOOC Flash Charge 3.0, this board is specifically engineered with thicker power traces and safety ICs to handle high-current charging safely. Below is the exhaustive technical product description and specification breakdown in a tabular format. 1. VOOC-Compatible USB Type-C Port The port is designed to handle the high 4A current required for VOOC charging. Standard boards often fail to trigger "Flash Charge" mode, but a high-quality Realme 5 Pro flex includes the necessary ID resistors to communicate with the original Realme 20W power adapter. 2. Digital Voice Microphone The primary call microphone is pre-soldered onto this board. It is specifically positioned to align with the bottom chassis hole. If your voice sounds muffled or callers can't hear you at all, replacing this board is the standard hardware fix. 3. Antenna Signal Terminal The small gold-plated circular terminal connects to the coaxial antenna cable. This is responsible for your 4G LTE/VoLTE network bars. High-quality boards feature full IC chips to ensure there is no signal loss or "Searching" errors after repair. Realme 5Pro CHARGING FLEX
