I²C continues to thrive as a standard for connecting microprocessors to sensors and other peripherals. Two major companies have adopted a standard connector for I²C called Qwiic, which makes I²C even more user friendly. Sparkfun chose a small JST 4 pin connector and Adafruit has also adopted the same connector for all of their I²C boards. Both companies sell a variety of boards using this connector, as well as inexpensive connectors and cables.
I have modified the seven I²C boards that are on this website to use this new smaller connector. The new versions of the boards are now available from Oshpark. Here is a list of my I²C boards.
Qwiic cables in various lengths are available from Adafruit, Sparkfun, Mouser, Digikey and Amazon.
The Qwiic surface mount connectors are available Mouser, Digikey,
Adafruit and Sparkfun.
