MCP4725 12 Bit I2C IIC DAC Development Board Breakout Board Internal EEPROM Store Settings for Arduino

These worked great. All the addresses sold by this seller are the same (2 addresses) so to get 4 addresses, I ordered the other version chips, and then soldered them on to two of these boards. Doing this, you can use up to 8 of these on the same bus. As for the chip itself, it is pretty linear, and the i2c support (and persistence of changes) works great.

Only able to get addresses 60 (all open) and 61 (any combination jumper across the address pad) to work. Bought 2 so tried both for address selection. Maybe I'm doing something wrong. Will look elsewhere to complete the project - probably the SparkFun board. Else they work fine with RPi.

I wasted a lot of time trying to get one of the two working. I assumed it was my problem. Switching to the second unit showed that it was not my problem. Amazon refunded the entire purchase price even though I only asked for half back.

Did exactly as intended, but would've been nice to include instructions on how to use multiple days.

I2C is very simple to use. Highly recommend these DACs.
