Re: [SlimDevices: Unix] pieCorePlayer hardware question
i have tried various voltage regulators from switch mode to venerable lm7805 to new generation low drop outs (LDO). There is a jump in sound quality when going from switch mode to linear. but then you have to deal with heat esp with rpi 3b+. with your pi zero which i also love above all pi's i would try one of the newer LDO's if you are drawing less then 0.5 A. http://www.ldovr.com/category-s/118.htm if you have more budget and enthusiasm and prefer discrete components over IC's these are super regulators: https://sjostromaudio.net/cart/en/super-regulators/17-419-ssr01-sjostrom-super-regulator-built.html#/21-output_voltage-5_v/27-voltage_reference-lm431 pi's and audio hats respond very well to the quality of the incoming power mcduman's Profile: http://forums.slimdevices.com/member.php?userid=66702 View this thread: http://forums.slimdevices.com/showthread.php?t=110091 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix

If I had all the bits and pieces, that's exactly what I'd do. Alas, I need to order them and don't have a scope at home to check the ripple. I figured I'd ask to see if anyone else has done something similar before going further.

hi rdb, Give it a go. I have a similar buck convertor I have been meaning to try. Its in my box of things to try! :D Maybe adding an additional cap on the RPi0 power input will help? regards Greg Greg Erskine's Profile: http://forums.slimdevices.com/member.php?userid=7403 View this thread: http://forums.slimdevices.com/showthread.php?t=110091 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
[SlimDevices: Unix] pieCorePlayer hardware question
I'm looking at building a pCP in an existing housing using a raspberry pi zero w and a DAQ. I have 24V, 18V, or 12V DC (clean) available from the existing power supply and was wondering what my best option is for stepping this down for the raspberry pi? Would a Pololu 5V, 2.5A Step-Down Voltage Regulator D24V22F5 work or is the RPi input going to be too noisy for audio?
