Power filter board for Rpi does not work?
![userHead](https://dfimg.dfrobot.com/dfPortrait2.png)
I’m using an iFI audio iPowerX with adapter socket from a circular power Jack into the Pi USB-C input and it has worked fine for several years as a media server running Volumio; when plugged into the new dfrobot power filter HAT power socket the lights on the Pi fire up for about a second and then slowly fade out. But back into USB-C it works fine.
Is it faulty?
I’ve written to the tech support email address but not received any reply so posting here for advice. My reseller (the Pi hut) says I need to ask dfrobot for a diagnosis before they refund or replace it.
Hi
Could you please try connect a more powerful power supply to Power Filter Board for Raspberry Pi 3B+/ 4B(DFR0940)? This fitler board may need more power to supply the board.
Hope it can help.
