- Specifications: Main IC: MCP4725; Communication interface: I2C; Converter resolution: 12 bit

Breakout module with the MCP4725 converter, a 12-bit DAC with I2C interface, which converts a digital value into a real analog voltage on the OUT pin, useful for signal generation, adjustable voltage references, and analog control in projects with Arduino, ESP32, STM32, or Raspberry Pi. It features internal EEPROM memory, an I2C address selectable via the ADDR jumper, and disableable pull-ups for setups with multiple modules on the same bus, with a supply of 2.7 - 5.5 VDC.
The MCP4725 module is a 12-bit digital-to-analog converter with an I2C interface, which allows a development board or a computer to produce a real analog voltage at the output, not just a filtered PWM signal.
