Yunir S220HS Bluetooth Power Amplifier Board - Dual 160W Stereo

In this review the Yunir S220HS Bluetooth Power Amplifier Board is presented as a budget-friendly, feature-rich module for DIY audio builders and compact home audio setups. The single biggest reason to buy is its dual TPA7498E chip design that delivers substantial power output while offering versatile inputs and app control, making it a practical upgrade for anyone who needs a compact stereo amplifier with Bluetooth and subwoofer support.

Key Features

• TPA7498E dual chip: Provides robust amplification across left and right channels so small to medium rooms get clear, powerful sound.
• Wide DC input range: Supports DC 12-38V which allows use with common 12 V and higher bench supplies for flexible installations.
• Multiple inputs: Bluetooth, 3.5mm AUX and USB inputs make it easy to connect phones, laptops and legacy sources without extra adapters.
• Gold plated DC port: 5.5x2.5mm large-current shielding port reduces sparking and improves connection reliability for repeated use.
• APP control: Allows basic configuration such as Bluetooth name and pairing settings through a companion app for more convenient operation.

Who It's For

The Yunir S220HS suits hobbyists building custom speakers, small home theater setups that need a compact stereo amp, and anyone wanting Bluetooth streaming plus wired inputs in a single board. Its power capability and subwoofer channel make it useful for tabletop systems and amp replacement projects where chassis space is limited.

People who need complete packaged receivers with built-in tuners, complex tone controls, or finished cosmetic enclosures should look elsewhere; this product is a component board meant for DIY integration and requires a compatible power supply and wiring know-how.

Pros & Cons

Pros

• High output from two TPA7498E chips gives strong stereo performance for the board's size.
• Multiple input options including Bluetooth and USB offer flexible source selection.
• Gold plated, shielded DC port and broad voltage tolerance improve reliability and installation options.
• App control simplifies Bluetooth naming and pairing compared with boards that lack configuration options.

Cons

• Supplied as a bare module so buyers must provide a suitable DC supply, enclosure and speaker wiring.
• No advanced tone or network features; it is a focused amplifier board rather than a full-featured receiver.
