Bluetooth 5.0 amplifier board for custom audio

This Bluetooth 5.0 TDA7498 digital amplifier board delivers 2x100W stereo output for DIY speaker projects. It accepts audio via Bluetooth 5.0, a TF card slot or an AUX input. The compact module suits builders adding wireless streaming to bookshelf speakers, desktop systems or portable enclosures. It is not for installations that require multi-channel surround decoding or balanced line-level inputs.

Thermals and power draw in normal use

The TDA7498 chip runs in Class D topology, so efficiency stays high and heat stays low at typical listening levels. A small heatsink on the board handles continuous music playback without fan noise. Idle current is minimal, and the board draws power only when audio is active, making it suitable for battery-powered or always-on setups.

Questions about this item

How do I install the TDA7498 board and which step do people miss?

Solder or plug the speaker wires to the left and right output terminals, connect a DC power source to the power input, insert a TF card if desired, then pair a phone using Bluetooth 5.0.

What maintenance or replacement will the TDA7498 board need later?

Keep the ventilation clear of dust and re-check the power and speaker connections if the sound cuts out; the TF card slot may wear after many insertions.
