Frequently asked questions
How do I connect it to an Arduino?
Connect SDA to the SDA pin and SCL to the SCL pin of the Arduino, with VCC and GND. Pull-up resistors on SDA and SCL are usually required, and the Arduino Wire library can access the chip.
How do I set the device address?
The A0, A1 and A2 pins set the I2C address bits. Connecting them to GND or VCC lets you use multiple EEPROMs on the same bus, as long as each has a unique address.
