4PCS MCP4725 Breakout Module I2C DAC 12Bit Development Board 2.7V to 5.5V Supply with EEPROM for Arduino Raspberry Pi
Description
- The MCP4725 is a single-channel 12-bit buffered voltage output DAC with non-volatile memory (EEPROM) that allows you to store configuration register bits (2 bits) and DAC input data (12 bits) to non-volatile EEPROM (14-bit) In memory. The DAC can be configured for normal mode or power-saving shutdown mode by setting the configuration register bits.
- The DAC allows you to send analog signals, such as sine waves, from a digital source such as the I2C interface on an Arduino microcontroller. Digital to analog converters are ideal for sound generation, musical instruments and many other creative projects.
- This version of the CJMCU-MCP4725 Breakout solves some of the board's problems, including IC packages, I2C pinouts, changing the overall board size to better suit your project, and some minor adjustments.
- The board breaks down each pin you need to access and uses the MCP4725 (including GND and signal OUT pins) to connect to the oscilloscope or any other device you need to connect to the board. There are also SCL, SDA, VCC and another GND for the basic I2C pinout. The device can be used with a 2-wire I2C-compatible serial interface and is powered by a single supply from 2.7V to 5.5V.
- If you want more than one MCP4725 on the bus, you can disable the pull-up resistors on this board.

Works as expected.
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.

Works but lacks documentation
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.

Works as expected
pros: cheap, working, small, red.cons: should have a pin for addr instead of the tiny solder jumper pads.

not all were good
one was bad ,

True analog output for your Arduino
Using to output low frequency audio (less than 1kHz) to an audio amplifier. Easy setup and easy to use.

DAC ok
Excelente para interactuar con MCUs

Don't be fooled by the lower price
1 of 4 circuits were missing/broken(see picture). The others looked ok. The packages had clearly been trampled.Price per item for this 'repacked and inspected' is not better than just a new item based given that not all boards are not operational. I will not do this mistake again.
