Gravity: GP8413 2-Channel 15-bit I2C DAC Module

SKU: DFR1073

DAC series modules use I2C or PWM to generate voltage (0-5V, 0-10V, 0-VCC) or current (0-25mA) outputs. They serve industrial automation (motor speed, temperature, light, valve control) with 8/12/15-bit resolution, single/dual-channel options, and cascading for multi-channel use. Compatible with Arduino, Raspberry Pi, STM32, they fit lab equipment, lighting, motor control. A 2-channel 15-bit model (0.01% linearity, 0-5V/10V outputs) has an I2C address switch, expandable to 16 channels via cascading—ideal for precise control like fine speed or angle adjustments.
