The MCP4725 is the DAC that will let you output analog voltages from a microcontroller. The CJMCU-MCP4725 is an I2C controlled Digital-to-Analog converter (DAC).A DAC allows you to send analog signal, such as a sine wave, from a digital source, such as the I2C interface on the for Arduino microcontroller. Digital to analog converters are great for sound generation, musical instruments, and many other creative projects!
This version of the CJMCU-MCP4725 Breakout fixes a few issues with the board including the IC footprint, the I2C pinout, changes the overall board dimensions to better fit your projects, and a few more minor tweaks. This board breaks out each pin you will need to access and the MCP4725 including GND and Signal OUT pins for connecting to an oscilloscope or any other device you need to hook up to the board.
Also on board are SCL, SDA, VCC, and another GND for your basic I2C pinout.
Additionally, if you are looking to have more than one MCP4725 on a bus, the pull-up resistors on this board can be disabled just check the Hookup Guide in the Documents section below for instructions and tips on doing this.
Features:
12-bit resolution
I2C Interface (Standard, Fast, and High-Speed supported)
They don't have the right item but when customer call for replacement they will say they don't have for this statement they will hold the customer call they will put in mute later they will say they don't have all are faulty item I've ordered for micro SD to micro SD but they have shipped SD to SD they are not ready to listen to the customer need also.
It is a great product for what it offers. The digital zoom is where it falls short in its clarity being digitally zoomed, but not very bad.
The optical lens is is brilliant.
Overall a great product at this price point.
