Nice little 5V SMPS.
Very nice and well designed item. The design proved to be safe with 4800V test voltage ( 10GOhm). Rudimentary EMI filter (common mode choke only), but MOV overvoltage protection and NTC inrush current limiting on input. Genuine (as far as I can say) Nippon Chemicon KXJ series 47uF bulk cap!
All caps are 105°C rated, although input smoothing one and output ones are TAICON brand, which is probably not the best as for longevity. The switcher IC is THX203H. The current feedback SOT23-6 opamp is marked G7P, which is not known to me.
Output current limiting function (!) kicks in at 2.3A.
Shame that the leads were snipped so short. Probably a discarded PSU from some device that did not psassed FCC compliance because of lacking proper EMI filtering. Apart form that, overall it is quite well designed and safe to use PSU.

Great little module.
The best part is that it uses UART communication, so it is extremely simple to communicate with. Just save your MP3s via the USB (UMS device), set 9600bps on your Arduino UART (or even terminal emulator) and send commands. The datasheet says that UART is 3V3 level only, but mine work fine with 5V UART.
The datasheet is here: www(dot)flyrontech(dot)com(slash)uploadfile(slash)download(slash)20164121013446051(dot)pdf
Recommended module to play with!

Pay or gtfo.
1 of 3 found this helpful I am not willing to review products for free. My time is precious to me and my skills adequate to do even some paid jobs. But the ink is OK, no problem. Do not afraid to buy it, it will do the job.
