Need help picking correct USB to UART adapter for AX9000

So i bricked my chinese AX9000 by incorrect flashing. (mixing up files, flashing the squashfs instead initramfs)
I already ordered a new one, so as someone who's never soldered i think this would be a good chance to get started trying

I am looking for the correct USB adapter to hookup to the UART pins (that i will attempt to solder on) of the router
I've ordered some pin headers, some dupont cables etc but i am confused about this 1.8v bit and what adapter to use.

I have been looking at this: CJMCU FT232H USB to JTAG UART FIFO SPI I2C IIC High Speed Multifunction FT232H Serial Port Module CP2104 from https://id.aliexpress.com/i/1005006112448661.html#nav-specification

Would this be correct?
Would i need some additional things besides the obvious soldering needs

Some help/advice would be greatly appreciated!
