ODEKTOOY 100W+100W 2.0 Channel Power Amplifier Board

ODEKTOOY ZK-1002T MAX is a compact 2.0 channel power amplifier board delivering up to 100W+100W using the TPA3221 chip with Bluetooth, AUX and USB inputs and an input-mode toggle switch.

This amplifier board combines high-output Class-D amplification with modern connectivity options so you can drive bookshelf or small PA speakers from a wide range of sources. It accepts 12–30V DC, integrates enhanced Bluetooth antenna options, and includes multiple hardware protections to keep the board stable under demanding use. The board is built for DIY audio projects, compact stereo systems, and upgrades where efficient power and flexible input switching are required.

How does the ZK-1002T MAX deliver high power in a small package?

The ZK-1002T MAX uses TI's TPA3221 Class-D amplifier topology that yields efficient power delivery and low heat compared with linear amps. That enables high continuous and peak output to speakers while keeping the board compact and suitable for fanless installations.

• Class-D TPA3221 chip for efficient 100W per channel peak capability.
• Wide supply range (12–30V DC) for flexible power options.
• Compact PCB layout for easy mounting in DIY enclosures.

What input options and switching controls are available?

The board accepts Bluetooth, 3.5mm AUX, and USB audio sources and uses a physical toggle switch to select the active input. The toggle provides a clear, tactile way to change sources without relying on remotes or apps.

• Bluetooth wireless streaming for phones and tablets.
• Wired 3.5mm AUX for TVs, computers, and legacy devices.
• USB input for direct digital audio from computers or media players.
• Dedicated toggle switch shows and selects the current input mode.

How is Bluetooth performance handled and improved?

To boost wireless reception the ZK-1002T MAX includes both an onboard antenna connector and an external IPX (MHF1) antenna base. This allows you to fit the external antenna where reception is better without soldering, improving range and stable connections in cluttered environments.

• Onboard Bluetooth radio for out-of-the-box wireless use.
• IPX (MHF1) external antenna base for longer range and fewer dropouts.
• No-solder antenna attachment for quick setup and repositioning.

What protection features keep the amplifier safe during use?

Multiple built-in protection systems reduce risk to the board and connected speakers by responding automatically to adverse conditions. These safeguards make it suitable for continuous operation in home or workshop systems.

• Short-circuit protection to guard speaker outputs.
• Over-current protection to prevent supply and component damage.
• Thermal protection that prevents overheating under heavy loads.

Who is this for: The ODEKTOOY ZK-1002T MAX is aimed at hobbyists, DIY audio builders, and small-system integrators who need a powerful, space-efficient stereo amplifier with modern inputs and robust protections. It's ideal for upgrading bookshelf speakers, building compact stereo rigs, or adding wireless streaming capability to a desktop or media cabinet where clear input selection and reliable Bluetooth reception matter.
