Fermion: PAM8403 3W Mini Audio Stereo Amplifier - W2.54 (Breakout)

This mini audio stereo amplifier from DFRobot offers left and right channels that deliver a stereo surround sound experience, enhancing audio output with remarkable clarity. Its compact form factor and 2.54mm pin pitch make it especially easy to incorporate into various devices where space is at a premium, providing versatility for integration into different projects.

Use this amplifier with a stereo enclosed speaker (FIT0502), eliminating the need for programming to control audio output. Whether building a DIY music box or enhancing a robot voice system, this module ensures powerful sound output from compact equipment. Its adaptability to various applications demonstrates its potential in creative sound modification projects.

This audio stereo amplifier features two distinct modes: sleeping and working. The module defaults to working mode, but the bias circuit can be closed by setting pin SHDN to Low (0V), switching the amplifier to sleep mode. Conversely, setting pin SHDN to High (5V) activates working mode, making it easy to control when the amplifier should engage or disengage.

Ensure proper installation by maintaining correct polarity and keeping the negative poles for high and low channels independent. The power supply must be a minimum of 5.5V to prevent potential damage from excessive voltage. This consideration ensures the module functions safely and efficiently, preserving its longevity and reliability.
