The HKD CJMCU-MCP4725 is a 12-bit I2C Digital-to-Analog Converter (DAC) breakout board, ideal for microcontroller projects requiring analog voltage output. Perfect for Arduino, ESP32, or other MCU applications, this DAC lets you generate smooth analog signals such as sine waves from a digital I2C interface. Common uses include audio generation, instrumentation, and creative electronics projects.
This version includes improved IC footprint, corrected I2C pinout, and optimized board dimensions for easier integration. It provides access to all necessary pins (GND, VCC, SCL, SDA, and Signal OUT), with optional pull-up resistors that can be disabled if using multiple MCP4725 devices on the same I2C bus. The onboard EEPROM allows you to store settings for consistent performance across uses.
Features:
- 12-bit resolution DAC for precise analog output
- I2C Interface: Standard, Fast, and High-Speed modes supported
- Supply Voltage: 2.7V - 5.5V
- Onboard EEPROM for storing configuration/settings
- Compact design for easy integration in embedded projects
Applications:
- Audio signal generation
- Musical instruments and sound effects
