3D Printed Bluetooth Mini HiFi

It is easy to build a mini hifi system of our own. All we need are a PCB with required features, a pair of speaker drivers and some accessories. Here is the list of materials:

1. Sanwu HF-71 PCB x 1
2. 2" speaker drivers x 2
3. Speaker cover x 2 (optional)
4. 4 positions speaker terminal x 1
5. 2 positions speaker terminal x 2
6. DC jack x 1
7. 12-24V DC power adapter x 1
8. Remote control x 1

The PCB packs with USB/MicroSD card playback, USB DAC, FM Radio as well as bluetooth connection.

It took quite a long time to print the enclosures, PCB enclosure - 7 hours , a pair of speaker enclosures - 10 hours.
