Datasheet

pulldowns, simply connect your button from the GPIO pin to 3.3V for an active-high

connection. You'll likely want to play music from a microSD card so we added a holder on-

board. And since we know so many of our customers use 5V microcontrollers like the

Arduino, we made the interface pins all 5V compliant with level shifters so you can use the

chip at 3V or 5V power/logic!

The breakout board comes fully assembled and tested. All v1.0 boards come with two

100uF electrolytic capacitors for line-level output coupling, v2.0 have the capacitors

integrated into the PCB. All kits come with some 0.1" male header you can solder to the

breakout so it plugs into a breadboard and a bonus stereo headphone jack that will be

handy when you want to plug headphones in!
