Wiring & Test

You can easily wire this breakout to any microcontroller, we'll be using an Arduino. For another kind of microcontroller,

as long as you have 4 available pins it is possible to 'bit-bang SPI' or you can use two I2C pins, but usually those pins

are fixed in hardware. Just check out the library, then port the code.

I2C Wiring

Use this wiring if you want to connect via I2C interface

Connect Vin to the power supply, 3-5V is fine. Use the same voltage that the microcontroller logic is based off of.

For most Arduinos, that is 5V

Connect GND to common power/data ground

Connect the SCL pin to the I2C clock SCL pin on your Arduino. On an UNO & '328 based Arduino, this is also

known as A5, on a Mega it is also known as digital 21 and on a Leonardo/Micro, digital 3

Connect the SDA pin to the I2C data SDA pin on your Arduino. On an UNO & '328 based Arduino, this is also

known as A4, on a Mega it is also known as digital 20 and on a Leonardo/Micro, digital 2
