HiFi DACs for Orange Pi – page 5 – Add-ons – OrangePi – Powered by Discuz! Archiver

Two projects are very similar.2) Orange PI PC with Kodi (I also would use OpenELEC, but my board have broken hdmi bus)
How did HDMI port brake?

4) Amplifier class D with ( TPA3116( class DI have make a class AB amplifier, almost working in Zone A, but now I’m not using that need to finish the preamplifier and box.)
I know the quality of class D is under some discrete classa A\AB amplifier )and, of course, vacum tube amplifier) but now some circuits have a good quality and the ratio qualitt/price is anwinble. The price of my multimedia center (i will put all inside one case) will be around 100 euro, but the quality of music will be medium/hight

With my dac at least I have no problems of background noise, and use an ordinary switching power supply.
in my case the 5V power suply is reduced inside the dac to 3.3V by a smd linear regulator. The dac is the first part of analogic signal, then i think i can have advantageusing a itium battery; so Sabre ES9023 run better with 3,6V power supply.

so i want in the future upgrade the ampli board with this changes: http://www.tforumhifi.com/t48121p325-tutorial-modifiche-tpa-3116-completo

Programming off the shelf CSR8635 module – Page 1

I recently bought a cheapie Bluetooth -> Stereo amplifier board. It works pretty well for what I need and I’m thinking about buying another. Unfortunately the device comes with “SANWU Audio” as the hard-coded BT device name. I’d like to change that to something nicer like “JamBox”, especially if I’m going to have two of these sweetpeas.

Has anyone had experience with re/programming these modules?

My stereo amplifier had this soldered on to it: http://www.dx.com/p/csr8635-2-channel-bluetooth-v4-0-module-black-blue-368089

Possible pinout for module: http://g04.s.alicdn.com/kf/HTB1Med2FVXXXXaIXFXXq6xXFXXXJ/220226238/HTB1Med2FVXXXXaIXFXXq6xXFXXXJ.jpg

I’m starting to think the “Debug SPI” on the chip (PDF: http://www.csr.com/sites/default/files/csr8635_qfn_technical_overview.pdf) isn’t exposed on the outside pins…
