Amplifier Module Bluetooth 5.0 USB-C Volume Control 2x 20W 4 Ohms
This amplifier module is a complete solution offering numerous operating possibilities. It features Bluetooth, USB-C Audio (16bit 44.1kHz), and 3.5mm AUX inputs. It also integrates a volume control with rotary knob, and audio output can be delivered either through a 3.5mm jack for headphone listening or via screw terminals with an amplification power of 2x 20W into a 4-ohm load. Versatile, this DIY module will fit perfectly into a desktop setup, especially since the included small PCB panels allow direct use without an aluminum enclosure.
Warning: output power depends on the power supply used.
The Bluetooth input has priority over USB and the 3.5mm jack. USB has priority over the 3.5mm jack.
The volume control does not manage the source device volume.
