“When all other voice recorders out there only seem to allow for 10 or 20 seconds of recording time, the Fermion voice recorder is out there on its own. 40 minutes of recording time! Allows for multiple, segmented recordings and always plays your last recording when you come back to it. Just need to figure out how to get this into a power-save mode so that my 500mAh LiPo can last longer than 48 hours. An on/off button? (I'm new to this). Left on, the Fermion's operating current is working out at about 10.4mAh. Very high-quality breakout board looking great in black and gold. For more controls (volume, next track, previous etc) check out the AD Key Board that works with it.”
