ISD1932 1964 8-CH Audio Sound Voice Record Play PCB, DIY Recorder Player Module

Description

This listing is for the bare PCB for making a sound record/play module.  No other electronic parts are included.  Please see links below for schematic and parts info.   Full technical support provided.
Onstate ARCM8 ISD1900 voice record/play module with audio power amp is for recording and playing back sound.  See Nuvoton ISD1900 series voice record/play IC datasheet for more information.  The ISD1900 series is very similar in function and control as APLUS aPR33A3 IC.  Digitally record sound, audio, voice and playback to speaker.  This sound module is useful for announcements, sound effects or theme projects such as Halloween or Christmas. The 1-8 messages can be accessed using a microcontroller or switch.
The Nuvoton ISD1900 ChipCorder Series is a single-chip multiple-message record/playback device with dual operating modes and wide operating voltage ranging from 2.4V to 5.5V.
Chip: ISD1900, 28-SOIC SMD
Voltage: 2.4-5.5V DC
Output: SY1, differential PWM Class D 8Ω speaker (SP+/SP-).
SY101, AUX voltage/current drive to ext amp (SP+/GND).
Sampling freq.: 4kHz -12kHz.
Control modes: Standalone push buttons, ground signal pulse or address bit input.
Memory: 100-year message retention (typical), non-volatile Flash.
Audio input: MIC+/MIC- differential with AGC or line-level analog in.
