The MCP4725 is an I2C controlled Digital-to-Analog converter (DAC)..
A DAC allows you to send analog signal, such as a sine wave, from a digital source, such as the I2C interface on the Arduino microcontroller..
On board are SCL, SDA, VCC, and another GND for your basic I2C pinout..
If you are looking to have more than one MCP4725 on a bus, the pull-up resistors on this board can be disabled just check the Hookup Guide in the Documents section below for instructions and tips on doing this.store settings.
Digital to analog converters are greInternal EEPROM to store settingsat for sound generation, musical instruments, and many other creative projects!.

This reference board is a very convenient tool to determine the position and function of each pin, which can make it very easy to connect the wire to the Raspberry Pi GPIO.
One side of the reference board shows the position, and the other side shows the GPIO number. You can view all the different pin labels of the 2×20 GPIO connector on the Raspberry Pi. By placing it on the connector or next to it, you can quickly check if any wires or components are properly connected.
Material: Raspberry Pi GPIO Plus reference pinout is made of glass fiber, and the holes of the reference plate are gold-plated Length: 60.2 /2.37in, width: 20.1mm/0.79in 100% high quality..
Use this reference guide to easily connect wires and components to your Raspberry Pi.
Compatible with Raspberry Pi models A+, B+, 2, 3 and 4.
