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.
