I2C lets you connect multiple I2C-compatible devices in series using only two pins. The controller will send out information through the I2C bus to a 7-bit address, meaning that the technical limit of I2C devices on a single line is 128. Practically, you're never gonna reach 128 devices before other limitations kick in.
