  • In Hall sensor nomenclature, the "3xx" series typically denotes a Unipolar Hall Effect Switch.
  • "Unipolar" means the sensor switches "ON" when a magnetic South Pole approaches and switches "OFF" when the field is removed (it does not require a North Pole to turn off, unlike a bipolar latch).
  • This series usually operates on a supply voltage of 3.3V to 24V.

Lossless Decoding: Supports high-fidelity formats like FLAC and APE, ensuring high-quality audio streaming.Compact Form Factor: Measuring roughly 30mm x 30mm, it fits into almost any enclosure.Auto-Reconnect: Automatically pairs with the last known device upon power-up.Low Latency: Bluetooth 5.0 technology reduces audio lag compared to older 4.0 modules.
