1002S 2.0 Bluetooth Amplifier Board with TPA3116D2 Chips - 100W+100W

Our review of the 1002S 2.0 Bluetooth Amplifier Board finds it best suited to hobbyists and small-system builders who want a compact, high-power stereo amp module with flexible inputs. The single biggest reason to buy is simple: it pairs dual TPA3116D2 chips for reliable Class D output and delivers a peak of 100W+100W from a wide DC 9-24V range, giving plenty of headroom for bookshelf or custom speaker projects while keeping the board easy to integrate.

Key Features

• Dual TPA3116D2 chips: Provides robust Class D amplification and high efficiency for clear stereo output that runs cool under moderate loads.
• Multiple input methods: Bluetooth, 3.5mm AUX, USB sound card and USB flash drive support make it simple to connect phones, laptops or legacy sources without extra adapters.
• Wide voltage range: Accepts DC 9-24V which allows use with a variety of power supplies and battery solutions for flexible installations.
• Input mode indicator: The input mode indicator light removes guesswork about the active source when switching between Bluetooth, AUX and USB modes.
• Multifunction knob: The main knob controls volume and supports press actions to switch tracks and input modes, reducing the need for extra controls.
• USB flash drive playback: Plays common formats like MP3 and APE from FAT32 drives up to 32GB for local file playback without another device.

Who It's For

The 1002S is aimed at DIY audio enthusiasts, makers and anyone assembling a compact home stereo or small powered speaker set who needs a high-power, feature-rich amplifier board. It is especially useful when Bluetooth streaming and USB playback are both desirable features in a single module.

It is less appropriate for those who need an all-in-one finished amplifier with enclosure, remote control or advanced tone controls; installers who require balanced inputs or professional rack gear should look for specialist pro audio amplifiers instead.

Pros & Cons

Pros

• High power output from dual TPA3116D2 chips that balance efficiency and sound quality.
• Flexible connectivity with Bluetooth, AUX, USB sound card and USB drive playback.
• Wide DC input range and upgraded DC socket for safer, spark-free connections.

Cons

• Board-level product requires external enclosure and wiring, so it is not a plug-and-play finished amp for everyone.
• No balanced inputs or built-in remote control, limiting use in some pro or home theater setups.
