Microduino-Amplifier is a D-Class Amplifier Module. Widely used in music embedded system.

|-
|
==Feature==
*2.54 Connector with good compatibility;
*Suppress power noise, gain stability;
*Small, cheap, stackable, opened platform
*Open source hardware circuit design, compatible with the Arduino IDE development environment for programming;
*Define unified interface Microduino specification and contain rich peripheral modules. Set up the quick connection with other Microduino modules and sensors easily and flexibly;
*2.54 pitch row female connector for easy integration into breadboard.

|-
|
==Specifications==
*Provide 2.2W output for 4Ω load;
*Operating Voltage：2.0-5.5V；
*Externally controlled, low-power shutdown mode, typical shutdown current of 0.7uA.

==Document==
Eagle PCB '''[[File:Microduino-LM4863.zip]]'''

===Main Component===
*Amplifier chip：LM4863 '''[[File:LM4863.pdf]]'''

==Development==
*Make sure the 5V power supply current can reach 500ma, not recommended use FT232R debugging directly, becasue FT232R's output current is small.

===Arduino library and supported package===
*【SimpleSDAudio library'''[[http://www.hackerspace-ffm.de/wiki/index.php?title=SimpleSDAudio download ]''' 】
*【SimpleSDAudio updated library '''[[File:Lib SimpleSDAudio.zip]]''' 】

===How to use the library===
*Original library SD module CS pin is D4, need change to D7;
*Original library can not directly support Microduino Core +, we have modified this library to solve this problem;

*Recommend 2GB or less (including 2GB) FAT format TF card.

===Externally controlled low-power shutdown===
*In many applications, the shutdown port's level conversion is finished by the controller, but it can also be used to implement by a one-way blade switch;
**Connect a pull-up resistor on the third pin of Second row pin female which near the D13 pin, then disconnect switch, this pin will be pulled low, so the Amplifier begin to work;
**Turn on the switch，pull-up resistor will pull up the voltage, then LM4863 stop work.

==Application==

===Program Download===
*Audio file conversion tool：'''[[File:Tools_lm4863.zip]]'''

===The Audio experiment using Core and SD===
*Prepared Hardware：Microduino FT232R、Microduino Core、Microduino SD、Microduino LM4863；
*Prepared Software：Arduino IDE（1.0 release upper）、Microduino provides test program（Arduino part）、SimpleSDAudio library、Audio file creation tools；
*Put the downloaded library to the libraries folder of Arduino IDE installation;
*Copy the "EXAMPLE.AFAM" in examples folder to memory card;
*Start Arduino IDE，open the "BareMinimum" program,card type chosse "Microduino Core (Atmega328P@16M,5V)",download directly；
*Then you can listen it！
**If you want to play your own audio, just need replace the "EXAMPLE.AFM" by you made audio file.

===The process to make an audio file===
*Convert any audio file into a. Wav format using a software "Format Factory";
*Generate an audio file：
**We need to use a SoX-based tool, and then choose the appropriate conversion process based on the operating frequency that your Microduino selected;
**Decompression the tool，then enter into“Arduino with 16 MHz”folder，put the audio file into this folder,and drag to "FullRate@16MHz_Stereo.bat" (16M full stereo) batch on；
**then you can convert the file, will pop up a dialog box appears "Press any key to continue ...";
**After completed, you will find a new folder, the converted file is there.
