This page has notes on how to use and work with the I²C modules.
The castelled edge connector of the standard module is designed for either header or direct-to-board soldering. The pins have standard 0.1 inch spacing, so fit popular headers and solderless breadboards.
We stock 10-packs of 4-pin right angle headers: hdrs.
Using with Arduino
Connect the module to the Arduino as follows:
Arduino sample code is given for each module. All the samples are here.
Soldering to a board
The four castellated holes on each module form a solder cup when held in place on a board like br3. Apply heat to the cup while adding solder. You can use tape to hold the module in place during soldering.
