Availability: Out of stock SKU: SSL1005 Category: Tags: , ,


  • ISD1700 voice module is designed for users who can quickly understand and use the ISD1700 series family chips. It applies to all ISD1700 series chip, with a simple, fully functional characteristics. Recording chip ISD1700 series is a highly integrated, high-performance chips.
  • It can be multi-segment recording, sampling rate can be adjusted from 4K to 12K, the power supply can range from 2.4V to 5.5V. ISD1700 there was the new recording prompts, when a new recording after, LED back flash once every few seconds to alert users to new recordings. In addition there are four kinds of sound to prompt the user’s operating results, such as start recording, stop recording, erase, erase all the next one and so on. Recording data is stored in the FLASH chip, without any compression, so there is a better sound quality and power storage.
  • Chip has two independent audio signal input channel, microphone input and analog signal inputs.
  • In independent key mode, when the operation is completed, a functional chip will automatically enter power-down mode to reduce power consumption. In SPI mode, the user can do more functions on the chip operation. If any memory address for playback on the analog channel configuration register (Analog PathConfiguration register, APC) for reading and writing.

Module Features:

  • Size: 5.2CM * 5.5CM;
  • Power: 5V;
  • Recording time: 6K time 75 seconds, 8K for 60 seconds;
  • Chip operating frequency 6KHZ and 8KHZ optional;
  • With power indicator light, the chip indicator lights;
  • Simple operation, no microcontroller or other modules will be able to work directly;
  • Chip control pin is already leads to facilitate the control connection

Compare to our ISD1820 Modules, it has following adavantage:

  • Longer recording time and mutiple message!
  • Controlled not only by buttons but also SPI from MCU
  • Better voice quality
  • And more expensive.

Click this button during playback to stop playback of the current segment and then play the next paragraph, if you are currently playing the last paragraph, the last paragraph playback to stop playback first paragraph.

4. Erase erase:

Single segment erase operation only work for the first and last paragraph, when the playback pointer in the first or the last paragraph, pressing this key will erase the first or last paragraph. Playback will jump to the corresponding pointer in the second paragraph before erasing or penultimate paragraph. Press this button more than 3 seconds often chips into the “All Erase operation mode” while the LED flashes twice, continue pressing this key, LED 7 flashes off, then release the button, the chip inside the voice message is All erased.

5. Reset RESET:

Click this button chip perform a reset operation. After reset, play and record pointer points to the last paragraph, which the playback pointer to the last paragraph of the initial recording pointer to the last paragraph of the last. Run the playback is played the last paragraph, the last paragraph and then perform recording then start recording new last paragraph.

 6. Tuning VOL:

Click this button to adjust the size of the chip output sound. The default maximum output sound chip, each click, the sound attenuation by 4db. Until the minimum of sound, continue press this button, click, the sound increases 4db (Note: you perform a reset, the sound output). 7. FT pass through operations: FT pin short connect with GND, continued on low TTL will  start passthrough mode. Straight-through the operation will voice from Analn end direct access to speakers or AUD output. During recording, if you press the FT, will also record the incoming voice signal Analn
