Anyone????????? Maybe it's OK because it has current limiting resistors?
Seem unlikely that this is safe.
I have noticed these type of "DASA" cables with zener regulation will emit -0.7V when the serial port has a negative voltage. This is outside the specifications for ATmega chips which have an absolute maximum negative voltage on I/O pins of -0.5V. Will this cable damage these devices?
No public wish lists :(
