DAMGOO 600W TPA3255 Bluetooth 2.0 Amplifier Board

The DAMGOO 600W audio amplifier board is a compact 2.0-channel TPA3255-based module that delivers up to 300W per channel with Bluetooth 5.2, AUX and adjustable treble, bass and volume for DIY wireless speaker projects.

Designed for hobbyists and small-scale audio builds, this DAMGOO amplifier board combines modern Class D efficiency from TPA3255 chips with flexible connectivity and protection features. It accepts DC 19–51V input, supports wireless streaming via Bluetooth 5.2, and exposes physical controls for treble, bass and multifunction volume, making it suitable for desktop systems, bookshelf speakers, or compact powered cabinets.

How much power can this amplifier actually deliver?

The board is specified to produce a combined 600W output, typically 300W per channel under appropriate supply and speaker loads. Real-world output depends on supply voltage, speaker impedance and thermal management, so pairing with the correct power supply and cooling yields best results.

• Rated output: 300W + 300W (dependent on voltage and load)
• Supply range: DC 19–51V — higher volts enable higher possible output
• Uses efficient TPA3255 Class D chips for high power density
• Thermal considerations: heatsinking and airflow recommended for sustained high power

What inputs and controls are available for connecting sources?

This board accepts multiple source types so you can stream wirelessly or connect wired players. Bluetooth 5.2 provides low-latency wireless audio, while AUX and USB options let you plug in older devices or local media players.

• Bluetooth 5.2 for stable wireless streaming from phones and tablets
• AUX input for analog connections to mixers or MP3 players
• USB sound card / USB flash drive support for direct playback
• Multifunction volume knob: volume, pause/skip and power on/off

What protection and reliability features are built into the board?

DAMGOO integrated several protective circuits to safeguard the amplifier and connected speakers during heavy use. These protections minimize the risk of damage from overheating, short circuits or excessive supply voltage.

• Overheat protection to reduce power when temperatures rise
• Overvoltage protection guards against supply spikes
• Short-circuit protection protects outputs and wiring
• Designed for stable operation when used with proper power and cooling

How can I fine-tune the sound for different rooms or speakers?

The board has independent treble and bass controls for quick tonal tailoring without extra processing. These analog adjustments let you compensate for room acoustics or speaker coloration at the source, while the volume knob handles level and simple transport controls.

• Separate bass and treble knobs for tonal shaping
• Quick adjustments for bright or bass-light speakers
• Volume knob also supports pause/skip functions for USB/Bluetooth playback
• Works well with passive crossovers or full-range drivers in DIY cabinets

Who is this for? Builders creating desktop stereo systems, bookshelf or compact powered speakers will find this DAMGOO amplifier board a practical core component. It suits DIYers who want high output in a small footprint, wireless streaming flexibility, and hands-on tone control. If you plan sustained high-volume use, pair the board with an appropriate DC power supply and a well-ventilated enclosure; for simpler setups, match with efficient speakers and moderate supply voltages to keep cooling requirements modest. DAMGOO also offers lifetime technical support for pre- and post-sale questions, which helps simplify integration and troubleshooting during DIY projects.
