BSV - (Bluetooth) Stereo Amplifier (Stereoverstärker)

The BSV project is based on a pcb with a transistor amplifier. It can be combined with a ]]>Bluetooth audio module]]> or with an audio jack only.

Hardware

There are two parts of the hardware. The pcb and the housing of the BSV. The pcb is created with KiCAD and the housing with FreeCAD. All files are built with github actions so that they are ready for a production environment. The housing is printed with a 3D-printer (Dremel 3D40).

PCB

The circuit board is populated on one side (Top). The best way for soldering is within a standard soldering system.

Mechanical

The housing has a tolerance of 0.2mm on each side of the case. So the pcb should fit perfectly in the housing. The tolerance can be modified with FreeCAD in the Parameter Spreadsheet.
