RS-232 level shifter on a small DB-9 serial connector.
Converts RS-232 signal levels - generated and required by your PC and
other devices - into the TTL levels needed by microcontrollers and most
robot electronics. This item may be used to interface your computer's
serial port directly to your electronics.
There is a DB-9 Connector on one end, a four pin female header
on the other.
A serial extension cable is needed to connect the
Serial Interface Connector to a PC. If you don't have
a cable, you can purchase one separately in our store. See
