This item is similar to the other MCP4725 modules out there are a couple of differences. Unlike some other vendor's modules, the address and pullup pads do not have a default setting soldered in place. So the address pin of the MCP4725 probably floats. This seems to work and the address comes up as 0x60 for me, but this state is not defined in the data sheet. If you have problems with the module not responding, you might scan your I2C bus and see if it's there and solder the pad to low or high. Also, the pull up pads are not jumpered together. This is fine if you have only one or two chips on your bus, the Arduino has (weak) pull up resistors enabled by the Wire library. YMMV may vary for other computers and bus configurations, so read the MCP4725 data sheet and study how I2C works to see if you need to enable the pull up resistors on the module. Aside from these minor differences, the module is a good value and ok if you want to add 1 or 2 DACs to your I2C bus. (Note: The maximum supported Arduino I2C clock speed is 400k, and this speed wont allow you to to generate more than about 16k data points per second. This is an Arduino specific limitation. The MCP data sheet days 3.4mbit is supported by the chip.)

The Python I2C code made an easy installation. Straight coding with none of the Arduino-style libraries required.

Works exactly as expected. Within ± .05V of SP have had no issues with dropout. Currently using 4 on I2C multiplexing with registry pin. Will buy more.

This work great but differ from the adafruit one a little bit. Took a long time to find the info I needed but for my project I remember I had to change some value that was 62 to a 60 for it to work with this module.
