Professional +3V to +5.5V, 250kbps, RS-232 Interface with Configurable Handshaking

Suitable for use in a variety of microcontroller and robotic projects, this RS-232 interface board provides a small and simple way to convert TTL and CMOS UART signal levels to those required by EIA/TIA-232 and V.28/V.24 specifications for RS-232 transmission at guaranteed minimum speeds of 250kbps.

Simple jumper configuration allows for hardware handshaking to be passed through or looped back, supporting many different applications.

Connections to the interface board can be made by the six pin single inline header.  A female 9 pin D-Sub connection allows for easy connections to PCs using a standard straight through cable.
