The Analog Test Board is an accessory board that includes an onboard Audio Power Amplifier (LM386M), two high-precision adjustable resistors used for adjusting the input voltage level (0-3.3V, 2 channel) and a speaker for indicating the output voltage level by sound volume (1 channel).

The board is ideal for testing AD/DA (ADC) functions that are integrated into many MCUs. The module also supports MP3 output to play music.

Don't forget to grab a handy pack of jumper wires for connecting to your development board!
