[QUOTE="dreambox1959, post: 1134377, member: 314801"] by definition, TTL technology is 5V but often the circuits in 3.3V are functional in 5V (to be checked in datasheet) FEMI what cable did you find in 3.3V?? on aliexpress there is many products USB to TTL with selectable voltages 3.3/5v even 1.8/2.5V but for my positioner we need 5V because of microprocessor inside (89s52).
