This is the bare board version (no connectors assembled) of the im1WP-TBPLUG and im1WP-TBPCB. For more details on this product, click on one of the two given links. 

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 TB05B-F350-W4 or TB05P-M350-H4 terminal blocks can be soldered into the space for a terminal block connector on the PCB. Any standard 2.54mm (0.1″) grid pin header, or press-fit pin header can be soldered into the two positions (X1 and X2) on the PCB left for pin headers. If required, wires can also of course be soldered onto the PCB in stead of connectors.
