SBC SOUNDMODULE-

Soundrecorder ISD1820

1. GENERAL INFORMATION

Dear Customer,

Thank you for choosing our product. In the following, we will show you

what to consider during commissioning and use.

Should you encounter any unexpected problems during use, please feel

free to contact us.

This sound module has a sound recorder and a playback device. It is

equipped with an ISD1820 chipset and has a recording time of about 8 to

20 seconds. It can be controlled via a built in keypad and has a 0.5 watt -

speaker and microphone.

2. CHANGING THE RECORDING TIME AND SAMPLING RATE

In this section we briefly explain the individual functions of the pins to

which you can connect your microcontroller or single board computer.

This is not a detailed explanation and only serves to explain the pins.

3. MODULE EXPLANATION

VCC: 3.3V Power supply.

GND: Ground connection.

FT (Feed Through): Allows the

microphone to be output directly to

the speaker.

P L (PLAYL): As long as the pin is HIGH -

the recorded is played.

P E (PLAYE): Plays the recorded once.-

REC: Is Active-HIGH and has priority

over the P E and P L signals. When - -

the pin is set HIGH, this activates

recording. The recording runs as long

as the pin is set HIGH. Not longer

than the set recording time.

To set the recording duration and sampling rate to a dierent value, it is

necessary to solder on a dierent resistor. The value of the resistor deter-

mines the duration of the recording and the sampling rate, which can va-

ry in the range from 8 to 20 seconds (with a sampling rate of 3 8 kHz). In -

the following picture the resistor to be changed is marked. A table shows

you which resistors are required for which settings.

Resistance value Duration Sampling rate Bandwidth

80K 8 Seconds 8.0KHz 3.4KHzΩ

100K 10 Seconds 6.4KHz 2.6KHzΩ

120K 12 Seconds 5.3KHz 2.3KHzΩ

160K 16 Seconds 4.0KHz 1.7KHzΩ

200K 20 Seconds 3.2KHz 1.3KHzΩ

FT Jumper (Feed Through):

Allows the microphone to

output directly to the speaker.

P E (PLAYE):- Play endlessly, Plays

the recorded over and over again.

REC: Is Active HIGH and has -

priority over the P E and P- -L

signals. When the pin is set to

HIGH, this activates the

recording. The recording runs

as long as the pin is set HIGH.

Not longer than the set

recording time.

P E (PLAYE): -

Plays the

recorded once.

P L (PLAYL): -

As long as the

pin is HIGH the

recorded is

played back.

Note with the included speaker that you have to solder the cables to it

yourself. Please note that you have to solder the cables in a certain way

in order not to mix up plus and minus.

On the back of the speaker you will find the solder pads where you have

to solder the included cable. Make sure that you solder the cable with

more points on the back to the " " of the speaker and the cable with + pad

the few points on the back to the " " of the speaker.- pad

Speaker connection:

The enclosed 8 Ohm 0.5 W speaker is

connected here.
