 Scurta prezentare Hobby Market Romania:

Modul inregistrare voce pe baza de ISD1820. Foarte simplu de folosit, fie prin actionarea butonului de pe device, fie prin atasarea la un microcontroller precum Arduino, etc.



This module is based on ISD1820, which is a multiple-message record/playback device. It can offer true single-chip voice recording, no-volatile storage, and playback capability for 8 to 20 seconds. The sample is 3.2k and the total Recorder time 20s. This module is very easy to use and you can directly control by pushing the button on board or by using a micro-controller such as Arduino, STM32, ChipKit etc. From these, you can easily control recording, playback, repeating and so on.



  • Push-button interface
  • Automatic power-down mode
  • On-chip 8R speaker driver
  • Signal 3V Power Supply
  • Can be controlled both manually or by MCU
  • Sample rate and duration changeable by replacing a single resistor
  • Record up to 20 seconds of audio
  • Dimensions: 37 x 54 mm

  • 1->PLAYE - Playback, Edge-activation: When a HIGH-going transition is detected, it continues until an End-of-Message (EOM) marker is encountered or the end of the memory space is reached.
  • 2-> REC - The REC input is an active-HIGH record signal.The device records whenever REC is HIGH. This pin must remain HIGH for the duration of the recording. REC takes precedence over either playback (PLAYL or PLAYE) signal.
  • 3->Speaker Outputs - The SP+ and SP- pins provide direct drive for loudspeakers with impedance as low as 8R.
  • 4-> MIC - Microphone Input, the microphone input transfers its signals to the on-chip pre-amplifier.
  • 5-> REPLAY - loop play the record.
  • 6-> FT - Feed Through: This mode allows use of the speaker drivers for external signals.
  • 7-> ISD1820 - IC chip
  • 9-> P2 - default short connection ROSC to 100KR resistance, that's means record duration is 10s
  • 10->PLAYL - Playback, Level-activated, when this input pin level transits from LOW to HIGH, a playback cycle is initiated.
  • You can also change the R2 to change the record duration. The Voice Record Module provides default connect 100k resistor through P2 by short cap. The default record duration is 10s.
