About the Bluetooth-Transmitter PCB

Bluetooth-Transmitter is an open source PCB design by hahmed14, published on GitHub. It is a 2-layer board measuring 45.8 × 50.3 mm, with 17 components from 13 distinct parts.

Other key parts include the FSC-BT1026E and TP4056-42-ESOP8. By type, the board carries 3 connectors, 3 LEDs, 3 capacitors, 3 resistors, 2 ICs and 1 switch.

It belongs with the audio and iot & wireless designs in this gallery.

From the project

Using bluetooth to revive the 3.5mm headphone jack and make it usable with modern devices with no audio port.

Big thanks to @dremeier for the Feasycom library, you can find it here:https://github.com/dremeier/Kicad-Bluetooth-Feasycom-projekt-library

Used KiCad for the original schematic and PCB design. You can send the Gerbers.zip file to any PCB manufacturer to have the board built. The BOM file specifes the exact part numbers at JLCPCB, you can have them manufacture the chip with all components attached but it'll be quite expesive. Otherwise order just the PCB for a couple dollers and solder the components yourself.
