## Description
|
||
|
||
**DAC HAT** is also a type of C-HAT specifically design for M5StickC controller. Same as DAC unit, this is a voltage output DAC converter for stickc. It can generate a voltage of 0～3.3V.
|
||
<br>
|
||
Packed with a DAC converter chip MCP4725, which is low-power, high accuracy, single-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC) with a non-volatile memory (EEPROM). Its on-board precision output amplifier allows it to achieve rail-to-rail analog output swing.
|
||
<br>
|
||
The DAC input and configuration data can be programmed to the non-volatile memory (EEPROM) by the user using the I2C interface command.
|
||
I2C address: 0x60
|
||
|

>1.EasyLoader is a simple and fast program burner. Every product page in EasyLoader provides a product-related case program. It can be burned to the master through simple steps, and a series of function verification can be performed.
|
||
|
||
>2. After downloading the software, double-click to run the application, connect the M5 device to the computer through the data cable, select the port parameters, click **"Burn"** to start burning. (**For M5StickC burning, please Set the baud rate to 750000 or 115200**)
