Raspberry Pi 2

February 4, 2015 Leave a comment Go to comments

Just a few month after introducing the Raspberry Pi B+, there is a new Raspberry Pi 2. It was reported that the Raspberry Pi 2 would be introduced in 2017 [link]. Maybe someone funded the entire upgrade (Microsoft?)

Same price, much more power and memory (actually those are the only updates: a new SoC chip and more memory)

The 2:


The B+


The SoC has been upgraded from the BCM2835 to the BCM2836. I will have to wait until someone posts the datasheet to compare the internal clock and audio capabilities of the two chips.

However, the hardware clock remains the same. Thus, same problems as before supporting audio sample rate frequencies [link]


The most interesting part perhaps is free Windows 10 for the on the Pi: [link].

Everyone and their grandmother are discussing the new RPI: I found these sites better than the rest…

    Hi, can we use this one with dam from Soekris?

      Yes. The RPI does not output a master clock and the DAC does not need a master clock signal as input

    Your blog always shows up when googling for Raspberry Pi, SMPS and HiFi.

    I am planing to go “modern” and go from traditional linear toroidal PSU to SMPS, but where can I find a good SMPS for HiFi??

    The SMPS needs to have at least one 5 volt output, maybe also another rail with 3.3 volt. And power, most are 1 amps, but I would prefer 2 amps or maybe 3 amps so that it will have the possibility to drive more future accessories.

    And of course clean enough current for HiFi and at a decent price 🙂

      I have not seen low voltage SMPS for audio, except what you can find inside in modern audio electronics. Even there, the designs are typical “industrial” SPMS but heavily filtered. You find higher voltage/power SMPS for audio because it is hard to find linear supplies regulated at that voltage and current. Computer supplies have 5V and 3.3V and the more expensive ones are actually cleaner, but not to the “standard” of HiFi.

      Maybe Hypex’s new SMPS developed for their DLCP can be used?

        It provides 2x16V. Can’t really be used for anything typically found in audio electronics unless you add further regulation…

    Can a Raspberry Pi2 be made to work with the Musiland 01 USD? – I put one on the front of my DAC, but never really got it to work because of the lack of a functioning Mac driver. there are some cool software options to use the Raspberry Pi as a streaming device but most depend on an interface board being added, which probably isn’t as good at the Musiland 01.

      I doubt it. Musiland requires a driver, in this case a unix driver (which I don’t think it exist). Last I checked, it does not behave like a standard audio device. It uses bulk transfer mode like a storage device: https://hifiduino.wordpress.com/2011/02/05/bulk-transfer-mode-in-musiland-monitor-devices/

      It appears the Musiland device is the only “hifi” consumer USB device that uses bulk mode transfer…The advantage of bulk transfer over Isochronous-asynchronous transter is the guaranteed nature of the data delivery. The advantage of Isochronous transfer over bulk is the guaranteed bandwidth; however if there is plenty of bandwidth available (for example, you are not maxing out the bandwidth of the USB connection by plugging in several devices), then guaranteed bandwidth is never an issue.

    Thanks for the reply. Very disappointed with the Musliand 01 .. no Mac Driver, and no RPi driver either. In fact it’s been a total waste of time and money as far as I’m concerned.

      You don’t need to be disappointed in this way. Musiland US01 works great in Windows setup an has a great driver which is absolute stable an very good sounding to its price.

        Hi, did you mean Musiland US01 work on RPi with Windows IoT?
