Gravity GP8630N I2C PWM DAC Module 10V

The DFRobot Gravity DFR1230 is a 16-bit digital-to-analog converter module based on the GP8630N chip with support for bipolar and unipolar output ranges. Unlike the single-channel GP8600, the GP8630N supports the bipolar ±10 V output range, which is required for direct motor control, bidirectional valve control, and laboratory applications with forward/reverse analog control. The 1.2 times over-range capability allows outputs up to ±12 V or up to 24 mA for systems that tolerate a slight excess of the nominal range.

Recommended Accessories:

• Gravity GP8600 I2C PWM 1-Channel DAC Module 0–10 V 4–20 mA
• FireBeetle 2 ESP32-E IoT Development Board 16M Flash 2M PSRAM
• Gravity 16-Bit 4-Channel ADC Analog Digital Converter I2C ADS1115

Features:

• 16-bit resolution with bipolar ±10 V output range for direct forward/reverse motor control and bidirectional valve control
• Flexible output ranges: ±10 V, 0–10 V, 0–5 V, and 4–20 mA – all configurable in one module
• 1.2 times over-range capability allows outputs up to ±12 V or up to 24 mA for tolerant target systems
• Up to eight configurable I2C addresses for multi-channel cascading on a single I2C bus without address conflicts
• Dual input control: I2C or PWM; operating voltage 3.3–5 V with Gravity PH2.0 connector for plug-and-play
• Compatible with Arduino, ESP32, and Raspberry Pi; example code available

Application Examples:

• Bidirectional motor control via ±10 V analog signal to servo controllers or inverters with forward/reverse control
• Precise laboratory applications with bipolar analog control signals for measuring instruments, test benches, and actuators
• Proportional valve control in hydraulic systems with bidirectional stroke via ±10 V signal
• Robotic joint position control with symmetrical analog output for precise servo drives
• Industrial PLC interface for analog signal generation with standard 4–20 mA or ±10 V protocol
