This is a miniature 0.7W amplifier with adjustable bass boost, gain, and volume controls. Uses 1/8" (3.5mm) headphone jacks on the input and output. Powered by USB or 9v (4-12 VDC, max of 15 VDC). I designed it to use film capacitors and Nichicon audio grade electrolytic capacitors wherever possible in order to preserve the signal and reduce noise. An isolated power supply such as a battery is...
supply AC6 - 12V to this and the circuit will convert the input to DC 5V (YOU CAN CONNECT A TRANSFORMER TO THIS).IT USES A RECTIFIER BRIDGE TO CONVERT FROM AC TO DC. theres not much to explain about this circuit so.. if you have any questions, plz ask in the comment section an ill repla ASAP.
hope you like my project ;)
PoE (Power over Ethernet) to USB 5V adapter.
Current use cases:
- Power micro controllers (Arduino's or Pbpi's)
PoE Switch --> **PoE to USB** --power--> Rbpi
