DAC is a unit that can convert digital signals to analog signals like voltage waveform, audio waveform, and so on. It integrates a 12-bit high-resolution DAC chip named MCP4725 which integrates an on-board non-volatile memory (EEPROM). The unit communicates with M5Core with I2C. The DAC input and configuration data can be programmed to the EEPROM. The I2C address is 0x60.
Excellent quality and fun
Everything as Expected. Thanks!
