A USB Type-C charging port on a mobile phone typically has 24 pins, which are organized to support various functionalities including power delivery, data transfer, and audio/video transmission. Here is a breakdown of the pinouts:
1. **A1/B12 (GND):** Ground pin.
2. **A2/B11 (TX1+ / RX1+):** SuperSpeed differential pair for USB 3.1/3.2 data transmission. **Issues: ( Fast charging not stable [May switch to 5v] or SlowCharging)
3. **A3/B10 (TX1- / RX1-):** SuperSpeed differential pair for USB 3.1/3.2 data transmission. **Issues: ( Fast charging not stable or SlowCharging)
4. **A4/B9 (VBUS):** Power supply (typically 5V, can go up to 20V with USB Power Delivery).**Issues: (Fake Charging) or It’s Faulty Battery(Iphone 0% Remaining) Check the both.
5. **A5/B5 (CC1 / CC2):** Configuration channel for cable orientation and plug detection. **Issues (Not Charging) Phone not detection of Charging.
6. **A6/B7 (D+ / D-):** USB 2.0 differential pair for data transfer.**Issues (SlowCharging)
7. **A7/B6 (D- / D+):** USB 2.0 differential pair for data transfer.*Issues: (SlowCharging)
8. **A8/B8 (SBU1 / SBU2):** Sideband use, for alternate mode functions (e.g., audio).**Issues (The handsfree microphone will not work)
9. **A9/B4 (VBUS):** Power supply.
10. **A10/B3 (RX2- / TX2-):** SuperSpeed differential pair for USB 3.1/3.2 data transmission.
11. **A11/B2 (RX2+ / TX2+):** SuperSpeed differential pair for USB 3.1/3.2 data transmission.
12. **A12/B1 (GND):** Ground pin.
NOTE :** DETECT PIN ON CHARGING CONNECTOR: ISSUE FAST CHARGING NOT WORKING!
These pins are symmetric, meaning the port can be plugged in either way and still function correctly, thanks to the duplicated pinouts. The configuration channel (CC1 and CC2) helps in detecting the orientation of the plug and manages the power delivery negotiations.
This versatile arrangement allows the USB Type-C port to support a wide range of functionalities with a single, reversible connector.
