Motivation
LeandraChristine needed a small solution for a project. Since I was designing lots of PCB’s anyway I decided to also realize this one.
Its es ment to be used with the SimpleSDAudio-library from Tut, who helped quite a lot with the circuit design in this project.
The board is carrying: Atmega328 MAX9098306 3.7W stereo Class D amplifier SN74LVC2G14 dual Schmitt-Trigger with its own low noise power supply microSD-Card Slot 74LVC1G53DP Analog Switch, to set the gain of the Class D amplifier (3 levels)
The controller itself is running on 3.3V (because of the SD-Card). The supply voltage is 5V.
