M5StickC DAC HAT MCP4725
The M5StickC DAC HAT is a plug-in module that adds a 12-bit digital-to-analogue converter (DAC) to your M5StickC. Built around the MCP4725 chip, it provides a single-channel analogue voltage output from 0 to 3.3 V, controllable via I2C.
The MCP4725 features non-volatile EEPROM for storing DAC settings and a rail-to-rail output amplifier, making it suitable for calibration, servo control, and sensor interfacing applications. It plugs directly onto the M5StickC header — no additional wiring required.
