## Description

The DFRobot Gravity 12-Bit I2C DAC Module is a compact digital-to-analogue converter based on the MCP4725 chip. It accurately converts digital values to precise analogue voltage signals, providing far cleaner output than PWM-based approaches from microcontrollers. With on-board EEPROM, the module retains its last DAC setting during power-off and automatically resumes output on power-up. An I2C address selection switch allows two modules to operate on the same bus (0x60 and 0x61). The included library supports generating sine, triangular, and arbitrary waveforms with just a few parameters. Key Features 12-Bit Resolution – Accurate analogue output from 0 V to VCC On-Board EEPROM – Retains DAC value during power-off for seamless resume Wide Voltage Support – Compatible with both 3.3 V and 5 V controllers Gravity I2C Interface – Plug-and-play connector with XH2.54 4-pin header for expansion Dual Address Selection – Switch between 0x60 and 0x61 for cascading two modules Waveform Generation – Built-in library functions for sine, triangular, and arbitrary waveforms Ultra-Low Power – Working current under 0.2 mA Specifications DAC Chip – MCP4725 Input Voltage (VCC) – 3.3–5.0 V Output Voltage – 0 V to VCC Resolution – 12-bit Working Current – <0.2 mA Interface – Gravity I2C (logic level: 0–3.3 V) I2C Addresses – 0x60, 0x61 (selectable via switch) Dimensions – 27 × 22 mm Weight – 13.8 g Ideal For Sensor calibration and testing Automatic control systems Function and waveform generation Precise voltage reference applications Arduino and Raspberry Pi projects requiring clean analogue output Resources Product Wiki & Documentation
