TTL-232R-5V and TTL-232R-3V3 Cables

The TTL-232R-5V and TTL-232R-3V3 cables are both terminated by a 6 way, 0.1”, Single-In-Line (SIL)

connector. The difference between the two cables is that the TTL-232R-5V operates at +5V levels (signals

and power supply) and the TTL-232R-3V3 operates at +3.3V levels (signals only, VCC= +5V).
