## Description

This Gravity DAC module converts I2C or PWM digital signals into stable analogue voltage or current outputs for control and automation projects. Built around the GP8630N chip, it supports output modes such as ±10V, 0-5V, 0-10V and 4-20mA, with 16-bit resolution available in I2C mode.The symmetrical ±10V output is useful for bidirectional control, such as driving motor controllers or valve actuators where positive, negative and zero voltages can represent forward, reverse and stop. It can interface with 3.3V and 5V logic, and supports 8 configurable I2C addresses for using multiple modules on one bus.It fits neatly into the DFRobot Gravity ecosystem and is suitable for Arduino, ESP32 and Raspberry Pi projects. The module is supplied with a Gravity-4Pin I2C/UART sensor cable and a Gravity-3Pin analogue sensor cable, with supporting documentation including a product wiki, schematic, dimension drawing, CAD/STP files, datasheet and calibrated accuracy test record.Typical uses include motor forward/reverse control, lighting brightness control, valve and pump control, signal generation and automation upgrades for small equipment.Features:Supports ±10V symmetrical high-voltage output for bidirectional controlProvides standard 4-20mA current loop output for industrial sensorsHigh 16-bit resolution with low full-scale error (±0.2%)Dual interface support: I2C and PWM input signalsCompatible with 3.3V-5V power supplies and Gravity interfaceSpecifications:Chip Model: GP8630NOperating Voltage: 3.3V-5VPower/Communication Interface: PH2.0-4Pin/3PinInput Signal: I2C / PWMCurrent Output Range: 0-24mAVoltage Output Range: ±12V/0-6V/0-12VNumber of Channels: 1 channelResolution: 16-bit (I2C mode)Resolution: 8-bit, 10-bit (PWM mode, selectable based on controller)Full-Scale Error: ±0.2% (measured after fitting calibration)Value Range - I2C Mode: 0-65535 corresponds to ±12V, 0-6V, 0-12V, or 0-24mAValue Range - PWM Mode: 0-255 or 0-1023 corresponds to output rangePCB Dimensions: 42 × 32 × 12.39 mmMounting Hole Spacing: 25mmMounting Hole Diameter: 3.0 mm
