Hardware Assembly

Now that we're familiar with the MCP4725 and the rest of this Qwiic breakout, let's connect it to a microcontroller to output some precise analog voltages.

Qwiic Assembly​

Since this is a Qwiic breakout, all you'll need to do is connect the breakout to a Qwiic-enabled development board like the RedBoard IoT - RP2350 like the photo below:

We've soldered headers to the PTH for easy prototyping and assembling the demo circuit to drive an LED connected to the voltage output.

Connect Analog Voltage Output​

Now connect the analog voltage output to whatever device you want to send the analog signals to. In this demo, we've connected that output to an LED to provide a nice visual representation of the signal:
