You can output analog voltages from a microcontroller using the MCP4725. The CJMCU-MCP4725 is an I²C-controlled digital-to-analog converter (DAC). A DAC allows you to generate analog signals, such as sine waves, from a digital source like a microcontroller’s I²C interface. DACs are useful for sound generation, musical instruments, and many other applications. This CJMCU-MCP4725 breakout board features improved design elements, including corrected IC footprint, optimized I²C pinout, and adjusted board dimensions for better integration into projects. All essential pins are broken out: GND, VOUT (analog output), SCL, SDA, VCC, and an additional GND. Onboard pull-up resistors can be disabled to support multiple MCP4725 devices on the same I²C bus. - PCB material - 12-bit resolution - I²C interface (supports Standard, Fast, and High-Speed modes) - Compact package - Operating supply voltage: 2.7V to 5.5V - Internal EEPROM for storing configuration settings - Appearance and silkscreen may vary slightly between batches; functionality is unaffected. - Color: As shown - Package includes: 1 × CJMCU-MCP4725 module - Note: Color representation may vary due to screen settings and lighting conditions. Dimensions may vary by ±1–3 cm.
