There are many different protocols and voltages for electronic communications. To get one device to talk to another you can use an adaptor/converter to change the voltage level or to translate between the different protocols like I2C, USB, RS285 and TTL Serial.
Computers tend to have only USB connections these days but small electronics typically use other light weight protocols so most of our adaptors connect from USB to one of I2C, TTL serial, RS485.
The SparkFun Qwiic Adaptor provides the perfect means to make any old I 2 C board into a Qwiic-enabled board. This adaptor breaks out the I 2 C pins from the Qwiic connectors to pins that you can easily solder with your favourite I 2 C-enabled device. More Details...
