Fermion Voice Recorder Module Breakout

The Fermion voice recorder module from DFRobot records speech and plays the recordings through a connected speaker; an amplifier is built in. With the buttons on the board this works without a microcontroller. It can also be controlled by an Arduino via UART, with AT commands or via ADKEY buttons. The 16 MB memory holds about 40 minutes in several segments. Via USB-C the module appears on the computer as a drive, and the files can be copied.
