Last year, Olimex launched A10-OLinuxXino-LIME powered by AllWinner A10, and it became quite popular due to its Linux and Android support, its open source hardware, and a price tag of just 30 Euros that made it cost competitive with BeagleBone Black and Raspberry Pi boards. The company has now designed an upgrade with A20-OLinuXino-LIME powered by AllWinner A20 dual core Cortex A7 processor, that sells for just 3 Euros more.
- SoC – AllWinner A20 dual core ARM Cortex-A7 @ 1GHz with Mali-400MP2 GPU
- System Memory – 512MB DDR3
- Storage – microSD card slot, SATA, and optional 4GB NAND Flash
- Video Output – HDMI 1080p
- USB – USB-OTG + 2x USB Hosts
- Connectivity – 10/100Mbit Ethernet
- Expansions – 200 GPIOs on 0.05″ connectors
- Misc – Lipo battery management and connector, buttons
- Power – 5V
- Dimensions – 84 x 60 mm
The specifications are exactly the same expect for the processor. The company will provide images and source code for Android 4.2.2 and Debian. Source samples, some tools, and hardware designs file are available in Olimex’s OlinuXino github repo. You’ve find any A20-OLinuXino-LIME hardware design files directly, simply because the board is the same for A10-OLinuXino–LIME as AllWinner A10 and A20 are pin-2-pin compatible. There’s supposed to be a Wiki for A20-OlinuXino-LIME (currently empty), but this will be very similar to the A10 version. U-boot and Linux kernel source code are mostly leveraging the work done by linux-sunix community.
Two versions of the board are now available: A20-OLinuXino-LIME without flash (boot from micro SD card) for 33 Euros ($45), and A20-OLinuXino-LIME-4GB that will include a 4GB NAND flash and sell for 43 Euros ($59).
