Analog Test Board with Audio Power Amplifier
Overview
The Analog Test Board is a specialized accessory designed for testing and evaluating analog-to-digital (AD) and digital-to-analog (DA) functionalities integrated within microcontrollers. This board features an onboard LM386M audio power amplifier, two high-precision adjustable resistors for fine-tuning input voltage levels (ranging from 0 to 3.3V across two channels), and a speaker that audibly indicates output voltage levels through sound volume on one channel. Additionally, it supports MP3 output and music playback capabilities.
Key Features
- Audio Power Amplifier: Integrated LM386M for enhanced audio performance.
- Adjustable Resistors: Two high-precision resistors allow precise control over input voltage levels.
- Speaker Output: Provides audible feedback of output voltage via sound volume.
- Versatile Testing Capabilities: Ideal for assessing AD/DA functions in microcontroller applications, as well as supporting MP3 playback.
