These adapters work great! Very easy to use. Sure you could make your own, but why? We have done the hard part for you!

Completely lead free!!!
Fully RoHS compliant

Do you need to interface to an I²C device? Need to evaluate a Dallas 1-wire IC? Are you developing a robot or maybe you are involved in testing a new cordless phone design? This board is for you! It will do it all!-- A must for anyone working with I²C devices!!! This Adapter will allow you to use a standard RS-232 serial port. and, makes it easy and fast to use I²C & SMBus devices with Computers to make fast,cheap, effective equipment. Support for SPI and Dallas 1-Wire gives you a world of chips to choose from.

Thousands of low-cost integrated circuits use serial buses: A-D's D-A's, LED and LCD Displays, I/O Ports, Radio chips, EEProms, Temperature Sensors, Relay Drivers, bus expanders, Analog Switches, Clocks, Counters, Frequency Synthesizers, Clock distribution amplifiers, MP3 Decoders, Audio IC's.......
