About this item

The CJMCU MCP4725 I2C DAC Breakout Development Board Module is a compact and efficient solution for adding digital-to-analog conversion capabilities to your microcontroller projects. Based on the MCP4725 chip, this module offers a 12-bit resolution, providing 4096 discrete voltage levels for precise analog signal output. It operates over a supply voltage range of 2.7V to 5.5V, making it compatible with both 3.3V and 5V logic systems. The module communicates via the I²C interface, utilizing SDA and SCL pins, which simplifies wiring and allows for multiple devices to share the same bus. Additionally, it features an internal EEPROM that stores the DAC output value, enabling the device to retain its output state even after power cycles. This is particularly useful for applications requiring a stable output without the need for continuous microcontroller intervention. The breakout board is designed with standard 0.1" pitch headers, facilitating easy integration into breadboards and prototyping setups. Its small form factor and low power consumption make it ideal for battery-powered projects, audio signal generation, and other applications where precise analog control is needed.
