SparkFun (PID 12918) I2C DAC Breakout - MCP4725

MCP 47:25 12-bit back with an I squared C interface generating a sine wave with 512 data points this is the version I'm using from eBay which has VCC ground the I squared C bus and an output analog voltage VCC can be 3.3 or 5 volts I'm using it at 5 volts and this module has an onboard jumper for one address select bit so you can have 2 unique addresses on the same bus if you have two of these modules the setup is very straightforward I'm using Arduino Uno the I squared C bus is going straight to the I squared C pins and also there's on-board pull-up resistors so I don't need any here this module from the Fritzing components is different from the one I have so I don't have this address pin I just have the onboard jumpers so the analog output is going to go to one channel of an oscilloscope I also generated a test digital output on output 2 to go to another scope channel and then there's
