M5Stack DAC I2C Unit MCP4725 Digital-Analog Converter

This DAC Unit from M5stack is a powerful 12-bit digital/analog signal converter. With this digital to analog converter, you can generate a sinusoid or use it for your audio projects to create tones. The DAC is controlled via the I2C bus and up to two MCP4725 can be operated on one I2C. If the mains voltage is interrupted, the last analog value is saved in the EPROM and restored as soon as operating voltage is applied.

Connect this DAC Unit to the GROVE PORTA on the M5Core or M5Stick. The i2C address is 0x60.
