MCP4725 I2C DAC Breakout Development Board

The MCP4725 DAC (Digital-to-Analog Converter) Breakout Board is a compact module based on the MCP4725 IC, which provides a 12-bit resolution digital-to-analog output using the I2C communication protocol.
It allows microcontrollers such as Arduino, ESP32, Raspberry Pi, STM32, PIC, etc., to generate precise analog voltages, which are not possible using simple PWM outputs.

The module includes a non-volatile EEPROM, which lets you store a DAC output value so it can be restored automatically after power-up. This makes it ideal for applications requiring a stable analog reference or output voltage.
