DFR1229

DFR1229 is a Gravity: GP8600 1-channel I2C & PWM to 0-5V/0-10V/4-20mA DAC module (16bit). This is a high-precision signal conversion tool designed to bridge the gap between digital microcontrollers and analogue industrial equipment. By converting I2C or PWM input signals into stable 0-5V, 0-10V, or 4-20mA outputs, this digital-to-analogue converter enables makers to control standard industrial hardware such as lighting systems, inverters, and valves using logic-level controllers like Arduino, ESP32, or Raspberry Pi. Unlike basic 8-bit DACs, this GP8600 converter offers a linearity error of just ±0.2% and supports cascading up to 8 devices, making the unit ideal for complex, multi-channel automation projects requiring fine-grained control.

• Industrial-grade signal conversion
• Flexible control & expansion
• 3.3V to 5V operating voltage
• Power/communication interface: PH2.0-4Pin/3Pin
• I2C/PWM input signal, 0-20mA current output range, 0-6V/0-12V voltage output range
• Resolution: 16-bit (I2C mode), 8-bit, 10-bit (PWM mode, selectable based on controller)
• Full-scale error: ±0.2% (measured after fitting calibration)
• PCB dimension is 38 × 32 × 12.39mm
