If you are using I2C products and want to adapt them to the Sparkfun QWIIC system, this board may help. There are 4 different pinouts available that all connect to the standard 4 pin QWIIC connectors. If the board you want to use does not match the standard breakout board that SF sells, then hopefully this board does. Typically you only need one of the 4 position .1" header pinouts (scl, sda, v, g). These 4 are arrangd so the V/G are crisscrossed along with scl/sda crisscrossed. This board has all 4 position headers rotated 90°.

This will solder directly to the SparkFun Electric Imp breakout https://www.sparkfun.com/products/11400 and adds RS232 Serial voltage levels to the Imp. Power and serial are all through an RJ12 6 pin connector. 1-GND, 2-+5V, 3-Tx232, 4-Rx232. Uses Uart57 on Imp. Chip is Max3232 http://www.digikey.com/product-detail/en/MAX3232CSE%2B/MAX3232CSE%2B-ND/947902 and all will fit very nicely inside this enclosure…. http://www.pactecenclosures.com/product-detail.php?productid=1393&seriesid=82&classid=25
