Title: Anyone have good shematic for K-line cable
Post by: BlackT on May 25, 2022, 01:45:02 PM
Okay I am sick of bad cables, in last 2-years anything I buy is a pice of sxxt
So I want to make my own, I have few FT232RL chips and what next?  To convert rx tx to K-line with transistors, OP AMP or to buy some special IC for that?
I need something that does not dissconect when there is a full moon or star is aligment in some special order

For K line to serial I think 9241A would be good choice
Does FTDI need some speial programing?

LM339 or a couple NPN transistors should work. I'll see if I have any schematics readily available.
