USB-DAC embedded Nutube headphone amplifier kit with USB bus-power operation.
I've enjoyed Nutube headphone amplifier, but the music source of headphone amplifiers is mostly USB output, for example Mac, PC, iPhone, iPad or smartphone. Even Raspberry Pi and NanoPi, Pocketbeagle has a USB-host function and they are capable of audio output through USB. If my Nutube headphone amplifier has USB input, it should be more useful and easy for enjoying "vacuum tube sound". The one thing we should care about is power supply, but this amplifier has built-in voltage booster and full USB bus power! (no more need of extra power supply).
USB-DAC (Ti PCM2704, 16bit, 48kHz) is embedded.
Embedded voltage booster enables full USB bus power operation.
Voltage booster operation frequency is 1.5MHz and no fear of audio interference.
Very small size!
Metal enclosure is included.
SMD parts are pre-soldered and USB-DAC function is fully examined before shipping.
Mellow vacuum tube sound with handy USB bus power!

From childhood, I've loved making electrical things by soldering for some amateur radio related thing.
After graduated certain university and taking Ph. D, I did have a GaAs MMIC design working for 60 GHz system
but it's a bit long time ago.
I always love making something and would like to share my joy. Please enjoy my store!
CAUTION!! I don't make and sell ESP32 related items anymore. If you need my board, (I don't have any relation with the items you will find, though..) please find at eBay or aliexpress with key components words ( For example, "ESP32" "ICS43434").
