Vhm 314 — Datasheet Free !!better!!

: Supports high-fidelity formats like FLAC and WAV for pristine sound quality.

A key detail for anyone seeking a datasheet is that the VHM-314 exists in several hardware versions. Forum discussions have identified at least , each potentially using a different core Bluetooth chipset, such as the AC1847AP1P803 , AS19AP , AS20BP , or AS22BP . This variation is the primary reason an all-encompassing datasheet is hard to find; documentation is often specific to the internal chip, not the module's generic product name.

The is a highly popular, ultra-compact, and cost-effective Bluetooth 5.0 audio receiver module . It is widely used by electronics hobbyists, hardware engineers, and DIY audiophiles to add wireless stereo capabilities to wired speakers, vintage amplifiers, and car audio systems.
