Wanna buy a simple & practical voice recorder? This one is right for you! The voice recorder module supports 4 controlling modes Arduino, AT command, on-board buttons and ADKEY, and multi-segment voice recording. You can directly press the on-board buttons to record or play voice without using a controller. Moreover, the 16MB storage on the module can store up to 40 minutes recording voice and the recorded files can be copied to your computer via the type-C interface.
