Jargon buster

Plain-language definitions for the technical terms used above.

Grove
Grove is a plug-in connector ecosystem for sensors and modules that avoids soldering and jumper wires. Grove compatibility matters because it can make it quicker to add supported I2C devices, as long as the cable and voltage are suitable.
