By converting I2C or PWM input signals into stable 0-5V, 0-10V, or 4-20mA outputs, this digital-to-analog converter enables makers to control standard industrial hardware—such as lighting systems, inverters, and valves—using logic-level controllers like \u003ca href=\"https:\/\/www.dfrobot.com\/topic-277.html\" target=\"_blank\"\u003eArduino\u003c\/a\u003e, \u003ca href=\"https:\/\/www.dfrobot.com\/topic-316.html\" target=\"_blank\"\u003eESP32\u003c\/a\u003e, or \u003ca href=\"https:\/\/www.dfrobot.com\/topic-272.html\" target=\"_blank\"\u003eRaspberry Pi\u003c\/a\u003e. 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.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cb\u003eIndustrial-Grade Signal Conversion\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eThe GP8600 DAC module excels in scenarios requiring compatibility with industrial standards. While many microcontrollers only output weak 3.3V analog signals, this converter boosts these logic signals to industry-standard 0-10V voltage or 4-20mA current loops. This capability allows the GP8600 to drive water pumps, servo motors, and heavy-duty lighting drivers directly. The inclusion of a 4-20mA current mode is particularly valuable for transmitting signals over long distances in noisy electrical environments without signal loss.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFlexible Control \u0026amp; Expansion\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eDesigned for scalability, the GP8600 16-bit converter supports 8 adjustable I2C addresses, enabling the simultaneous control of up to 8 independent channels from a single microcontroller interface. This feature simplifies the wiring for multi-axis motor controllers or complex LED arrays. Additionally, the device accepts a wide 3.3V-5V power supply and utilizes the standard Gravity PH2.0 interface, ensuring plug-and-play compatibility with the DFRobot ecosystem and widespread platforms like STM32 and Raspberry Pi.\u003c\/p\u003e\u003ch2\u003eApplications:\u003c\/h2\u003e\u003cli\u003eMotor \u0026amp; Inverter Control: Precise 0-10V speed regulation for variable frequency drives (VFDs).\u003c\/li\u003e\u003cli\u003eSmart Lighting Systems: Flicker-free, high-resolution dimming for 0-10V LED drivers.\u003c\/li\u003e\u003cli\u003eFluid Automation: Accurate position control for 4-20mA proportional valves and water pumps.\u003c\/li\u003e\u003cli\u003eLab Signal Generation: Creating custom voltage waveforms for testing sensors and analog circuits.\u003c\/li\u003e\u003cli\u003eDevice Retrofitting: Converting legacy analog appliances into smart, microcontroller-managed devices.\u003c\/li\u003e\u003ch2\u003eSpecification:\u003c\/h2\u003e\u003cp\u003eBasic Parameters\u003c\/p\u003e\u003cli\u003eChip Model: GP8600  \u003c\/li\u003e\u003cli\u003eOperating Voltage: 3.3V-5V  \u003c\/li\u003e\u003cli\u003ePower\/Communication Interface: PH2.0-4Pin\/3Pin  \u003c\/li\u003e\u003cli\u003eInput Signal: I2C \/ PWM  \u003c\/li\u003e\u003cli\u003eOutput Signal:  \u003cbr\u003e     Current Output Range: 0-20mA  \u003cbr\u003e     Voltage Output Range: 0-6V \/ 0-12V\u003c\/li\u003e  \u003cli\u003eNumber of Channels: 1 channel\u003c\/li\u003e  \u003cli\u003eResolution: \u003cbr\u003e     16-bit (I2C mode)  \u003cbr\u003e     8-bit, 10-bit (PWM mode, selectable based on controller)\u003c\/li\u003e  \u003cli\u003eFull-Scale Error: ±0.2% (measured after fitting calibration)\u003c\/li\u003e  \u003cli\u003eValue Range:  \u003cbr\u003e      I2C Mode: 0-65535 corresponds to 0-6V, 0-12V, or 0-20mA  \u003cbr\u003e     PWM Mode:0-255 corresponds to 0-6V, 0-12V, or 0-20mA, 0-1023 corresponds to 0-6V, 0-12V, or 0-20mA\u003c\/li\u003e  \u003cp\u003e\u003c\/p\u003e\u003cp\u003ePhysical Dimensions\u003c\/p\u003e\u003cli\u003ePCB Dimensions: 38 × 32 × 12.39 mm\u003c\/li\u003e\u003cli\u003eMounting Hole Spacing: 25mm\u003c\/li\u003e\u003cli\u003eMounting Hole Diameter: 3.0 mm\u003c\/li\u003e\u003cp\u003e\u003c\/p\u003e\u003ch2\u003eDocuments:\u003c\/h2\u003e\u003cli\u003e\u003ca href=\"https:\/\/wiki.dfrobot.com\/SKU_DFR1229_GP8600:%20I2C%26PWM%20to%200-5V%260-10V%264-20mA%20Module\" target=\"_blank\"\u003eProduct wiki\u003c\/a\u003e\u003c\/li\u003e\u003ch2\u003eProduct Includes:\u003c\/h2\u003e\u003cli\u003eGravity: GP8600 1-Channel I2C \u0026amp; PWM to 0-5V \/ 0-10V \/ 4-20mA DAC Module ×1  \u003c\/li\u003e\u003cli\u003eGravity-4Pin I2C\/UART Sensor Cable ×1  \u003c\/li\u003e\u003cli\u003eGravity-3Pin Analog Sensor Cable ×1\u003c\/li\u003e","brand":"DFRobot","offers":[{"title":"Default Title","offer_id":42343283458130,"sku":"DF-DFR1229","price":32.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0735\/0383\/files\/DFR1229_Main_01.jpg?v=1774161897","url":"https:\/\/www.pakronics.co.nz\/products\/gravity-gp8600-1-channel-i2c-pwm-to-0-5v-0-10v-4-20ma-dac-module-16-bit-df-dfr1229","provider":"Pakronics®","version":"1.0","type":"link"}
