REDMI NOTE 7/7S/7PRO CHARGING Board

The Redmi Note 7 / 7S / 7 Pro Charging Connector Board (also known as the Charging Sub-Board or CC Board) is a multi-functional internal PCB module. Because these three models share a common internal architecture for their lower docking station, this single part is compatible across the entire Redmi Note 7 series.

It is responsible for power delivery, data synchronization, and houses the primary microphone. Below is a comprehensive breakdown of the product.

1. Power & Fast Charging

The board features a reinforced Type-C port designed to handle high-amperage charging. It is fully compatible with Quick Charge protocols, ensuring your phone reaches 50% charge in approximately 30 minutes (when used with a compatible adapter).

2. Audio & Communication

The Primary Microphone is soldered directly onto this board. This component is responsible for picking up your voice during regular phone calls and voice recordings. Replacing this board is the standard fix for "caller cannot hear me" issues.

3. Network Signal Integrity

The board contains the RF Antenna Terminal. This is where the coaxial signal cable connects to the bottom of the phone. A high-quality board ensures that your 4G/LTE and Wi-Fi signal strength remains stable.
