TrillBit's TrillConnect app makes IoT device setup, device error communication, and diagnostics seamless with it's data over sound technology. When configuring an IoT device to connect to a network is typically complicated. The Trillbit DemoKit shows how Trillbit’s Data Over Sound technology can connect your IoT device to a network quickly and easily. The Trillbit DemoKit is built using a Raspberry Pi 3 B+ with a custom Trillbit hat. The hat has two MEMs microphones, an OLED display, a pair of status LEDs and a large reset button.
