  • SoC – AllWinner A20 dual core ARM Cortex A7 @ 1.0 GHz, with Mali 400MP2 GPU
  • System Memory – 1GB DRAM
  • Storage – 4GB NAND Flash, SATA connector, and microSD card slot (up to 32GB)
  • Video Output – HDMI 1.4 with HDCP support, LVDS header
  • Audio Out –  3.5mm analog audio interface, I2S stereo digital audio interface
  • Connectivity – Gigabit Ethernet, 802.11 b/g/n WiFi
  • USB – 1x USB host, 1x USB OTG
  • Expansion Headers – Arduino UNO extension interface with 14xGPIO, 2xPWM, 6xADC, 1xUART, 1xSPI, 1xI2C.
  • Camera – MIPI camera support
  • Misc – IR receiver
  • Power – 5V, 2000mA, support for Li-Po Battery
  • Dimensions – 121mm x 65mm

The board can run Ubuntu 12.04 / 14.04, Fedora, or Android 4.2 with the images available on pcDuino3 Nano / pcDuino3B download page. Documentation, and tutorials are available on pcDuino3 page.

pcDuino3B sells for $59.99 on Linksprite store plus shipping, except if your order exceeds $99 in which case shipping is included. How you also find it on Ebay for $55 including shipping (Title refers to pcDuino3B, but description is for the 10/100M version, so better ask first). If you are based in Europe, you could consider order from EmbeddedComputer.NL or LDLC for a little over 60 Euros including VAT in order to avoid potentially nasty surprises from your local customs office.

  1. It would be very interesting to know if these boards also show the unexpectedly high difference in transfer speed of sata disk reading and writing?

    With a disk that performs at 120MB/s reading and writing to a x86 board, with A20 cpu’s I always measure 120MB/s for reading (which is excellent) and only 30MB/s for writing (which is very slow!!).

  2. @cnxsoft
    Your measurements show an even bigger discrepancy: 180/36 = 5 times faster reading.

    Has anybody an educated guess what does slow down writing 4-5 times???

  3. @cnxsoft
    Many thanks for guiding me towards that single publication of linuxengineering. It is very interesting what he obtained with a rather limited hardware.

    I will have to understand the technical details and then try to apply it to A20 on my BananaPI and pcArduino nano. I still hope that it is not hardware because I have bougth too many A20 and spent a lot of time learning to build mainline kernel, uboot’s and so on….
