Gravity GP8600 I2C PWM 1-Channel DAC Module 0-10V 4-20mA

The DFRobot Gravity module with the GP8600 converts an I2C or PWM signal into a voltage of 0 to 5 V or 0 to 10 V or into a current of 4 to 20 mA. This lets an Arduino, ESP32 or Raspberry Pi control devices with analog input, such as frequency inverters, LED drivers with 0-10 V dimming, proportional valves or pumps. Via I2C the resolution is 16 bit, the error after calibration ±0.2 % of full scale.

Note: The connection cables can be converted to male pins with a Dupont cable M-M, so that they also fit an Arduino UNO.

Recommended Accessories:

• Dupont Cables M-M 10cm 20 Pieces
• FireBeetle 2 ESP32-E IoT Development Board 16M Flash 2M PSRAM

Features:

• Output on screw terminal OUT and GND: 0 to 5 V, 0 to 10 V or 4 to 20 mA, raw ranges 0 to 6 V, 0 to 12 V and 0 to 20 mA
• I2C mode: 16 bit, range set by software, address with DIP switches A0 to A2 from 0x58 to 0x5F, up to eight modules on one bus
• PWM mode via input D: 8 or 10 bit depending on the controller, range via DIP switches (A2 A1 A0): 000 for 0 to 6 V, 010 for 0 to 12 V, 110 for 0 to 20 mA
• Important: In PWM mode A0 must not be set to 1, otherwise the module can be damaged (DFRobot)
• Two Gravity connectors: I2C (+, −, C, D) and PWM (−, +, D)
• Supply 3.3 V to 5 V
• Library DFRobot_GP8XXX and calibration guide in the wiki

Application Examples:

• Set the speed of frequency inverters via 0 to 10 V
