# DFRobot_GP8403
|
||
|
||
This I2C to 0-5V/0-10V DAC module can be used to output voltage of 0-5V or 0-10V. It has the following features:
|
||
1. Output voltage of 0-5V or 0-10V.
|
||
2. It can control the output voltage with an I2C interface, the I2C address is default to be 0x58.
|
||
3. The output voltage config will be lost after the module is powered down. Save the config if you want to use it for the next power-up.

## Summary
|
||
The Arduino library is provided for the I2C 0-5V/0-10V DAC module to set and save the output voltage config of the module. And the library has the following functions:
|
||
1. Set the voltage of 0-5V or 0-10V directly；
|
||
2. Output the corresponding voltage by setting the DAC range of 0-0xFFF；
|
||
3. Save the voltage config(Will not be lost when powered down).
|
||
|
||
## Installation
|
||
1. To use this library, first download the library file<br>
|
||
```python
|
||
sudo git clone https://github.com/DFRobot/DFRobot_GP8302
|
||
```
|
||
2. Open and run the routine. To execute a routine demo_x.py, enter python demo_x.py in the command line. For example, to execute the demo_set_current.py routine, you need to enter :<br>
|
||
|
||
```python
|
||
python demo_set_current.py
|
||
or
|
||
python2 demo_set_current.py
|
||
or
|
||
python3 demo_set_current.py
|
||
```
|
||
|
||
