Compact DIY amplifier board

The ARRAROWN ZK-1002T PRO is a 2.0 channel stereo amplifier module built for DIY speaker projects. It accepts Bluetooth 5.0, USB and AUX inputs and runs from a 12 V to 24 V DC supply. The board measures 4.4 inches by 2.75 inches by 0.78 inches, so it fits inside small enclosures.

Dual 100 W channels with clear limits

Two TPA3116D2 chips deliver 100 W per channel into a suitable load, giving 200 W total output. The signal-to-noise ratio exceeds 90 dB and distortion stays below 0.1 % at high power. Bluetooth range reaches 15 m (49 ft) line of sight, but the module has no Wi-Fi, no multiroom streaming and no phono preamp for turntables.

Bluetooth 5.0 with QCC3003 chip

The QCC3003 Bluetooth 5.0 receiver pairs quickly with phones or tablets and maintains a stable link up to 50 ft. AUX input requires the Bluetooth link to be disconnected first. This single wireless interface decides whether the board matches a builder’s source devices.

Questions about this item

Will the 2.0-channel output on this ZK-1002T PRO board drive passive speakers I already own?

Yes, the module delivers 100W per channel into a 2.0 stereo load, so any passive speakers rated for that power range can be connected directly to the speaker terminals.

How can I verify the TPA3116D2 chips are operating within their 0.1% distortion spec after installation?

Play a clean test tone at moderate volume; if the output remains clear with no audible artefacts and the board stays cool, the chips are performing within the rated distortion figure.

Does the package include a power supply for the 12-24 V DC input, or must I source one separately?

Only the amplifier board itself is included; a 12-24 V DC power supply capable of delivering sufficient current for 200 W total output must be purchased separately.
