Hello.
I'm sorry if I'm posting in wrong forum.
I bricked my router and I need a UART to unbrick it. I'm new to UART's and stuff like that and I don't know what UART to choose. One guy told me mostly I need 3.3V. That UART will be okay https://www.ebay.com/itm/Metal-case...CP2102-STC-PRGMR/222503843286?epid=1250535213 ?
Also I find in my local shop this USB To TTL Adapter FTDI FT232RL, jumper 3.3v-5v, USB, it will be okay ?
I just read that in case I use a 5V UART on a device where 3.3V need to be used it could blow the chip
On router back it says 24V-2.5A
If I need to provide some more info just say it and I will do it

The device in the link operates on 5v but for the price it would be cheap/easy to see if it operates on 3,3v.
Why did he say you need 3.3v?
The device is not a UART, but appears to be a USB/COM port converter by the look of it?

What make/model of router? What did you do to cause it to be bricked?
