Troubleshooting
Start with the symptom you can observe. Apply one change at a time, then measure between VUSB and GND again.
| Symptom | Check | Fix |
|---|---|---|
No 5 V on VUSB with a USB-C charger or a USB-C to USB-C cable | The board has no resistors on CC1 and CC2. A USB-C power source waits for them before it turns the 5 V on. | Connect a 5.1 kΩ resistor from CC1 to GND and another from CC2 to GND. A USB-A to USB-C cable supplies 5 V without them. |
| Your device needs a faster link than USB 2.0 | The board carries only D+ and D-. It has no SuperSpeed pairs. | Use USB 2.0 speeds with this board. |
| The board does not sit in the breadboard | The header pins come unsoldered. | Solder the header to the bottom of the board, the side opposite the socket. |

- product name and SKU: 3x Soldered USB-C female vertical connector breakout,

- the voltage you measure between
VUSBandGND - how the pins are wired, and whether
CC1andCC2have resistors - a clear photo of the wiring
