SKU: DFR0972
This is an I2C DAC module that outputs 0-25mA current. It offers more accurate 4-20mA current output after calibration, which can be used with most 4-20mA devices on markets such as motors, inverters, valves, pumps, etc., by Arduino programming.

This article offers an in-depth look at the API functions for initializing and controlling current modules, focusing on I2C pin configuration, DAC value settings, and methods for calibration.
FAQ
Is it possible to change the i2c address of the DFR0972?
Hi, the I2C address of the DFR0972 cannot be modified at present. If there is an address conflict with other I2C devices, you can use the Digital 1-to-8 I2C Multiplexer to solve this problem. The product link is: https://www.dfrobot.com/product-1780.html
For the subsequent versions of this product, we plan to add an additional MCU chip to enable the function of switchable I2C addresses.
