voltage input value (0 to 3.3 V, 2 channel), and listenning to
trumpet sound can know voltage output value (1 channel)
4,Typical Application: Support testing MCU with the AD/DA
function,testing whether MP3 output is normal or not,testing music
playing
5,The main resources: LM386M, speaker, high precision adjustable
resistor x 2, testing interface
6,Applicable to a variety of platforms including Arduino/AVR
/ ARM
