SKU CH-J4EY-C0M9J

  • Bluetooth 5.0 streams audio wirelessly up to 10 metres
  • Built-in 2×3 W amplifier drives speakers directly
  • FM radio covers 87.5–108.0 MHz for local stations
  • USB and TF slots play MP3 and WAV files
  • Signal-to-noise ratio of 89 dB keeps playback clean

Product identity

This is a compact Bluetooth 5.0 audio receiver board with a built-in 2×3 W amplifier, FM tuner and slots for USB and TF storage. It runs from a 5 V DC supply and is aimed at DIY installers adding wireless streaming to a car, a workshop speaker or a small home audio project.

Suitability

It suits anyone who wants a single board that handles Bluetooth, FM radio and local file playback without a separate amplifier. Buyers who need more than 3 W per channel, a display, recording capability or battery operation should look at a different module.

Deciding specification

The critical figure is the 2×3 W output into 4 Ω loads from a 5 V rail; if your speakers demand higher power or a different supply voltage this board will not drive them adequately.

Questions about this item

How do I install this receiver in a car and which step is often done wrong?

Connect the DC 5 V supply, attach speakers to the 2×3 W amplifier outputs, then pair via Bluetooth 5.0; the step often missed is securing a stable 5 V source so the amplifier does not shut down under load.

What maintenance or replacement will this receiver need later?

The unit has no internal battery and relies on external power, so the only upkeep is checking the 5 V supply and cables; flash memory storage and the FM tuner (87.5–108.0 MHz) have no user-serviceable parts.

What limit appears first during sustained use?

The 2×3 W amplifier can overheat at continuous high volume, triggering thermal protection before the 89 dB signal-to-noise ratio or Bluetooth 5.0 range (5–10 m) become limiting factors.
