Vesper Technologies Inc - Preliminary Version

The VM1010’s Wake on Sound mode brings voice activation to battery-powered

consumer devices — while drawing nearly zero power, making it ideal for voice-

interface devices such as smart speakers, TV remotes, smart earbuds, and smart

home products.

The VM1010 has a small 3.76 mm X 2.95 mm X 1.3 mm package and is reflow

solder-compatible with no sensitivity degradation. It operates in environmentally

harsh surroundings because it is dust- and moisture-resistant.
