Description: 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 jhttp://www.electronics123.com/shop/category/kits-and-modules-audio-amplifiers-323ust has to be momentarily pressed to replay the message. A second momentary press during playback will stop the playback. Sampling rate is 12KHz. All you have to add is the speaker (not included) and 5V DC power (not included). We also have an A93010A-kit which in addition to the part# A93010A also includes a speaker and two cable connectors to connect the unit to a power supply (not included) and the speaker.

NOTE: This unit will power a 1 watt speaker as is. You do not need to add an external amplifier. However, you can add an external amplifier if you want to drive more than a 1 watt speaker, as long as you follow one of the 2 options below.
HOW TO ADD AN EXTERNAL AMPLIFIER:
METHOD 1: (Best Option)
METHOD 2: (Alternate Option)
Use this schematic to add a potentiometer when using an additional external amplifier:
When using an external amplifier, you'll need a potentiometer to decrease the high output signal from the A96010 enough to get a clear sound.
