PLEASE NOTE: YOU ARE BUYING THE SOLDER PAD VERSION. NOT THE TERMINAL BLOCK VERSION DEPICTED HERE:
K1, K2, K3, and K4 are Normally Open (N.O.) manual buttons.
TX port and RX port are used to connect with an MCU, through which serial commands are sent to control the module.
Version 2.0 The Busy port outputs a low signal when the module is playing a sound. High signal when the module is in standby.
Use this board to build a Sound Glove. See details on this page
Make this module motion activated: External PIR Motion Sensor PIR-001 or PIR-002
