1-Wire Interface Module with I2C bus, 3.0V-5.5V, Lead Free.



 Description

The im1WP is an electronic module with an I2C accessible 1-Wire interface, and press-fit connectors. It is part of the Modtronix Presto 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 www.maxim-ic.com. It has press-fit connectors for easy integration onto a target board, with no soldering required. It can be mounted on a custom board, a prototype board (like Veroboard), or one of our Presto SBC Boards. The im1WP is part of the Modtronix Presto iMod product range.

The im1WP has two rows of press-fit connectors on the bottom of the board. They can be pressed into 1.00mm holes on a 1.6mm thick (standard PCB thickness) target board. No special tool is required, they can be inserted by applying firm pressure to the connectors. Once fitted to the target board, the board is very secure, and can not be removed by hand any more. A screwdriver or similar tool can be used to remove the board if required. If the im1WP is to be soldered onto the target board, 1.10mm holes can be used. This will allow it to be inserted much easier than with 1.00mm holes. When using 1.10mm holes, the board can be removed by hand.
