Using this voice recorder module is a breeze. First, connect it to an 8Ω 3W speaker or an external active speaker for audio output. If you want to use it with an Arduino - compatible microcontroller, connect it via the 3 - pin digital interface. To record, just press the record button, say what you want, and let go of the button when finished. The module can play back up to 10 seconds of your recording. Remember to use a 5V power supply as that's its operating voltage. It can handle up to 100,000 recording cycles, but don't over - stress it. For maintenance, keep it in a dry and clean place. Avoid exposing it to extreme temperatures or moisture. If you have any questions, refer to the product WIKI or other available documents.
