APR33A3 Voice Recorder and Playback Module
APR33A3 Voice Recorder and Playback Module, which is a powerful audio processor with high-performance analog-to-digital converters (ADCs) and digital-to-analog converters (DACs).
With the APR33A series, the user can record and play voice messages averaging one, two, four, or eight messages at a time by switching the switch. Resistors are used to adjust the sample rate. It is suitable in a simple interface or needs to limit the length of a single message, e.g. toys, leave messages system, answering machine, etc.
Arduino, 8051, PIC and other microcontrollers can be interfaced with by soldering the Berg header directly to the port pins, and sending an active low signal to activate the button. The low signal period varies with the duration of the recording message, and a single low pulse plays back the message.
