Standard RS232 serial could be as much as -15 to +15 (30v full swing) as opposed to the 3.3v/TTL that is required by the A64/RK3399 used in the Pinebook/Pinebook Pro. Meaning depending on how true that cable is to the spec, at minimum it could fry the RX/TX GPIO pins, and possibly fry the CPU completely.
Information on the pinout, baud rate, etc is here on the wiki.
Thank you.
Given that USB only provides 5V I highly doubt the cable can deliver 15V. Anyway, the CPU is alive.
Grumbling mode on.
This should've been written in capital letters right next to the audio port! It shouldn't have been made secret information only an elite group of people knows!
Grumbling off.
