20 second voice recorder/playback module (A93010)
 
PLEASE NOTE: This module, part# A96010, is actually an A93010. It is virtually identical to the A96010 and it operates the same, but downloadable datasheets are available for each for comparison if necessary. The small size is because the IC is in Chip-on-board form. One button is pushed down to record the message through the on-board electret microphone; A LED turns on during this time. The other button just has to be momentarily pressed to replay the message. A second momentary press during playback will stop the playback. Sampling rate is 4K. All you have to add is the speaker (not included) and 5V DC power (not included). We also have an A96010-kit which in addition to the part# A96010 also includes a speaker and two cable connectors to connect the unit to a power supply (not included) and the speaker. The record/play time is determined by the 52K resistor. If you change it to 89K you will get 30 seconds but at a reduced sampling rate. Operating current 25mA. Standby current 10 uA. Size: 34 x 23 x 11 mm. The module comes supplied as you see it in the photo. 

OPTIONAL ITEMS (Not included):
2 x (BB089) connector cable to connect the voice recorder to a speaker and power source.
1 x (PB244) Speaker
1 x Battery holder that can hold either 4 x AAA or 4 x AA or 4 x C or 4 x D cells. See our battery holders.
