This sensor comes in an easy-to-use metal can. You can easily solder it or plug it into a breadboard. The four pins are used for power, ground, i2c clock and i2c data. There are two versions, one for 3V power and logic levels and one for 5V power and logic levels. This item is the 5V version! - good for use by classic Arduinos. You'll also want two 10K pull-up resistors for the I2C data lines, which we thoughtfully include.
Of course, we wouldn't just hand you a datasheet and wish you luck, we've written an easy-to-use tutorial & Arduino library with an example that will have you up and running in 5 minutes. The code can also be ported to any microcontroller with i2c support.
