About

George Ioakimedes of IO Technologies, LLC (a USA based company) is announcing the availability of their Baseboard for Cubieboard. This is a very important addition to the Cubieboard community.

As George explains it. “A Baseboard is a developer board and, like the Cubieboard, is very extensible and can connect to a variety of devices including sensors. To simplify the connection to additional devices, it is common to have an additional printed circuit called daughterboard or baseboard. This board is a baseboard, because it acts as a base to the Cubieboard. The Cubieboard can take power from this baseboard.”

Specs:

  • 2mm pitch female sockets to accept Cubieboard
  • All 96 Cubie pins brought out to 0.100" pitch headers
  • LVDS header w/ separate LCD Backlight connector to match low cost LVDS cable
  • 4-wire touch screen connector
  • Standard 2.1mm DC jack, 12V-18V input
  • Onboard 5.0V switching regulator to power Cubie and provide 3A (available on 0.100" header)
  • Onboard 3.3V switching regulator to power LCD and provide 3A (available on 0.100" header)
  • 15W Stereo Class D Audio Amplifier
  • VGA circuit and HD15 connector
  • 10cm x 10cm

CubieNOS

About

CubieNOS is what it sounds like. It’s a Non Oversampling (NOS) Dac. It’s designed by HIFI enthusiasts for enthusiasts and DIY people.

“Our main focus is on best possible and natural sound and not numbers like total harmonic distortion.” – George at G2 labs

The idea is simple. Low number of components with a well thought out PCB design for shortest signal path possible. Early balanced stage in the digital signal path and fully balanced the whole way through with dual Philips D/A converters and a Burr Brown buffered output stage with enough power to drive low impedance headphones. And of course, no capacitors in signal path.

CubieNOS is produced in two different versions, either in a NOS configuration or with a fixed output with a frequency at 176.4 kHz.

Output:

  • L/R Balanced XLR
  • L/R Unbalanced RCA
  • L/R Unbalanced headphones 2.54mm pin (header CON_1)
  • Alphanumeric displayport 2.54mm pin (header CON_2)
