Polyvector says the board offers features comparable to chromecast audio however in a module that is completely open supply.
A berlin developer has released the voltastream 0, a hand-crafted and open-supply included audio module inside the same form as a raspberry pi zero.
Despite the same shape to the raspberry pi zero, the voltastream zero from polyvector is a wholly one of a kind platform, thanks to its in-constructed texas instruments (ti) digital audio converters (dacs). Their inclusion partially explains the voltastream zero’s rate, which starts offevolved at €50 ($52) in comparison with the raspberry pi zero’s $5.
The opposite is the small scale of the voltastream zero production, presently being made in batches of as much as 100.
The audio board has an exciting tale, though. It’s the outcome of polyvector founder philip voigt’s 4-12 months quest to ideal an in advance model cobbled together with a raspberry pi and attached dac.
The very last result has similar capabilities to chromecast audio however in a module this is completely open supply and delivered via a “one-guy show”.
Even the physical layout of the board is open source, primarily based on cern’s kicad pcb designs. The hardware files are to be had on polyvector’s github page.
Voigt based polyvector in 2013 to begin paintings on the incorporated audio board, which he by myself designs and manufactures today. He assets center components from nxp and ti, however in any other case manufactures the board himself with his own choose-in-vicinity machine, stencil printer, and reflow oven.
He additionally has a laser cutter to carve the board’s elegant timber case, and maintains its linux kernel, drivers and the three like minded running systems: polyos, polybian, volumio.
“i suppose i’m currently the simplest one generating a business however open-supply linux board in a one-man display,” voigt advised zdnet.
Explaining the high charge, voigt points out that its soc, nxp’s i.Mx6ull arm cortex-a7 996mhz processor, alone prices as plenty as the whole raspberry pi 0. He chose the soc for top notch supplier assist, strong documentation and coffee electricity intake.
“then, of route that dac is expensive in addition to the blended 3.5mm trs jack that offers get right of entry to to both analog line output or optical toslink audio. Also, the pcb is populated on each sides which means that a doubled manufacturing time in comparison with raspberry pi 0,” he stated.
“ultimate however not least, i am sourcing the additives in quantities of 100, not 100,000 or even tens of millions like producers of different forums.”
While small volumes upload to expenses, voigt reckons he can ramp up production faster than if he outsourced assembly, which is fortunate due to the fact most effective 5 devices are currently to be had.
Voigt has enough additives to turn out a hundred more boards.
“i just need to hit the start-button to ramp up stock once more. Even though i might run absolutely out of stock, new additives will take much less than 14 days to arrive,” he stated.
He is also imparting a custom builds for orders of more than 30 devices.
The voltastream zero is available with ddr3 512mb or 1gb ram, and editions of ti’s dacs. It additionally functions a sizable usb type a connector, a microusb port, and 28 gpios.
