Overview
1. The Analog Test Board is an accessory board includes an onboard Audio Power Amplifier LM386M, and two high-precision adjustable resistor used for adjusting input voltage level (0-3.3V, 2 channel), and a speaker for indicating the output voltage level by sound volume (1 channel).
2. The board is ideal for testing AD/DA function that integrated in the MCUs, it also supports MP3 output, music playing, etc.

Features
LM386M, speaker, high-precision adjustable resistor × 2, analog input/output
