What is it?

This is a custom-designed Bluetooth + DAC + Amplifier module made exclusively for my LilyGO T-Display S3 based Internet Radio project (refer to my other listings here for more details about the products it can connect to).

The board integrates:

📡 A Bluetooth audio module for streaming music to:

Bluetooth speakers

Bluetooth headphones

AirPods and similar devices

🔊 A MAX98357A chip functioning as:

I2S Digital-to-Analog Converter (DAC)

3W Class-D audio amplifier

The module is designed with the exact same header layout as the LilyGO T-Display S3, allowing it to connect directly to the board headers without adapter wires.

It is not a standalone product and works only with my official Internet Radio firmware.

Why did you make it?

I designed this module to provide a clean, compact, and fully integrated audio solution tailored specifically for my Internet Radio project.

Instead of combining separate Bluetooth boards, DAC modules, and amplifiers, everything is integrated into one optimized PCB that:

Matches the LilyGO header layout

Works directly with my firmware

Reduces wiring complexity

Makes the DIY build much cleaner and more reliable

What makes it special?

🎵 Dual audio capability

Stream audio via Bluetooth to external devices

Drive a speaker directly using the MAX98357A (3W output)

🔌 Direct header connection – shares the same layout as the LilyGO T-Display S3

🔧 Designed specifically for my Internet Radio firmware

📐 Compact PCB optimized for this exact project

🛠 Ideal for DIY builders

🚫 Not a universal module — works only with this radio design
