WTR050M01 is a recordable voice module, long recording distance, good sound quality, can directly drive 8Ω/0.5W speaker. Through key control, long press to record, besides, it has other functions, such as loop playback, short press to play. WTR050M01 voice record module can perfect replace ISD1820, but the price is lower than it. Also provide voice record chips, thanks to contact us for more detail. Features:☆Working voltage: 2.8V ~ 5.2V.☆Automatically into sleep mode when not working.☆Recordable, recording time up to 50s.☆Key functions: Long press to record/ not play in a loop, short press to loop playback/ play.☆Amplifier directly driving 0.5 W/8ohm speaker.☆Record and play prompt, can connect LED display.☆Sampling Rate 8KHz~ 16KHz, ...
OverviewWTN3 series IC is single-chip CMOS speech synthesis IC, Now there are two models WTN3 040 and WTN3 080, the length of time for 40 seconds and 80 seconds (6K sample ratio). With an Input pin and two I / O pins , With accurate internal resistance shock (+ / - 1%), so no add external shock resistance, only one PWM output, there is no need plus any component. Speech synthesis method is 4-bit/5-bit Mixed Advanced LOG-PCM, with a 9-bit PWM hardware output ,can provide better sound quality. Features(1) Programmable one-time burn (OTP) voice chip;(2) Voice length of the optional 40 seconds, 80 seconds (6KHz sample rate);(3) PWM audio output mode;(4) Integrate of the internal clock oscillator, without external shock resistance;(5) OKY1 support up to 32 segments voice;(6) Push-button co...
