The im1WP is an electronic module with an I2C accessible 1-Wire interface. It is part of our iMod product range.  It enables devices on a 1-Wire bus to be read and written to via an I2C serial bus. It has special circuitry to enable long distance communication on the 1-Wire bus. It uses the Dallas DS2482-100 I2C to 1-Wire Bridge chip. For details on DS2482-100, dowload it's datasheet from Maxim's web site.

The im1WP has two rows of standard 2.54mm (0.1") pin headers. The rows are 0.7" apart, allowing this module to be mounted on a breadboard or standard 0.1" grid prototype board. The picture to the right shows some iMod modules mounted on a standard prototype board.

The pin headers supplied or soldered to this board are selected in the "Header Type" option at the top of this page.
