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

Hello so basically i found a github that offers the ability to turn an FTDI to an SPI programmer, and also found a tool on a chinese Forum to

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

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…
