Pyle TW100U 100W Mono Amplifier Board

The Pyle TW100U is a compact mono amplifier board built around the TPA3116D2 chip and rated for 100W output. It accepts a DC 12-24V supply and includes a built-in step-up circuit that can raise internal voltage to 19V or 24V. Bluetooth 5.3, 3.5mm AUX and USB inputs give DIY builders flexible source options for passive speakers or subwoofers.

Bluetooth 5.3 TWS pairing range and stability

Bluetooth 5.3 provides the wireless link and supports True Wireless Stereo pairing between two TW100U boards for left and right channels. The module includes an antenna base for an external antenna to improve coverage in larger spaces. Audio quality and connection reliability will still depend on the source device implementation, local interference and antenna placement.

Check power supply voltage and speaker impedance

Verify that your DC power source stays within the 12-24V input window and can deliver enough current for the desired output level. Confirm that the passive speakers or subwoofer you plan to drive present a load the TPA3116D2 chip can handle safely. The board has no internal battery, so continuous wired power is required for operation.

Questions about this item

Should I choose the 12V or 24V supply to get the full 100W output?

The built-in boost circuit steps the input up to 19V or 24V internally, so the board delivers its rated 100W mono output across the whole 12-24V DC range.

What does the 100W mono rating mean when I connect a passive speaker?

The TPA3116D2 Class D chip provides up to 100W into a single channel, giving enough clean power for most DIY bookshelf or subwoofer drivers at low distortion.

How does Bluetooth 5.3 with TWS change the way I wire two boards?

Two TW100U boards pair wirelessly over Bluetooth 5.3 to form a true wireless stereo link, removing the need for an inter-board cable while keeping L/R separation.
