# UART
With TTL-UART make troubleshoot uncomplicated!
| SoC | Total Pin | RX Pin | TX Pin |
|-------------|-----------|--------|--------|
| `RTL9601CI` | `76` | `13` | `12` |
| `RTL9601D` | `88` | `16` | `15` |
For `GND` and `VCC` (3.3) you need **SFP Breakout Board** to power it via external source, TTL-UART (`CP210x`) not enough power!
If you unable to get **SFP Breakout Board**, you can get [SFP Seat (without cage)](https://www.aliexpress.com/item/1005001701209420.html) and power that way.
To avoid solder XPON Stick, use [**Flying Probe**](https://www.aliexpress.com/item/1005002848489450.html) to connect tiny pin into tiny pad.
