ODEKTOOY T300HS 300W+300W TPA3255 Bluetooth Amplifier

The ODEKTOOY T300HS is a compact 2.0-channel power amplifier board using the TPA3255 chip, delivering up to 300W+300W with Bluetooth, AUX, and USB inputs for vehicle and desktop audio projects.

Compact but powerful, the T300HS combines a modern Class D TPA3255 amplifier stage with multiple input options and robust protection features. Designed for custom car audio installations, DIY speaker systems, and compact desktop amps, it supports a wide DC input range and continuous operation thanks to a large passive heatsink. The board integrates onboard and external Bluetooth antenna options, a user-friendly input selector switch, and safeguards like short-circuit, over-current, and over-temperature protection.

How loud and clean is the T300HS for car or home use?

The TPA3255 amplifier core provides high-efficiency Class D amplification capable of producing up to 300W per channel under appropriate power and speaker conditions. Expect strong dynamic headroom and low power loss when paired with a suitable 19–51V DC supply; actual output depends on supply voltage, speaker impedance, and thermal environment.

• Maximum rated output: 300W + 300W (dependent on voltage and load)
• Recommended supply: stable 19–51V DC for full performance
• Class D topology for efficiency and reduced heat generation
• Large heatsink for improved continuous operation

What input options and connectivity does the board offer?

The T300HS supports Bluetooth wireless streaming, 3.5mm AUX input, USB audio via a sound card interface, and playback from USB flash drives. A physical input-mode toggle switch makes switching sources simple and shows current input selection at a glance.

• Bluetooth: onboard and external MHF1/IPX antenna base for better reception
• Aux-in: 3.5mm line input for phones, players, or line-level sources
• USB: accepts USB sound card input and USB flash drive audio files
• Input switch: tactile selector for fast source changes without menus

What protection and reliability features are built in?

Safety and long-term reliability are addressed with multiple hardware protections to prevent damage from common faults. These protections let the board be used in vehicle and DIY environments where voltage or load conditions may vary.

• Short-circuit protection to guard speaker outputs
• Over-current protection for abnormal draw situations
• Over-temperature protection assisted by the heat sink
• Designed for continuous operation within specified voltage range

Who is this for: The ODEKTOOY T300HS suits hobbyists, car-audio installers, and DIY builders who need a powerful, compact amplifier board with flexible inputs and dependable protection. It’s ideal for upgrading factory systems, powering bookshelf or custom speaker cabinets, or integrating into compact multimedia enclosures where Bluetooth and USB playback are required. Users should be comfortable wiring DC power and speakers, and selecting an appropriate power supply and speaker impedance to match desired output and thermal limits.
