Recently most development around AllWinner, at least for Linux, is focusing on AllWinner A20, and there are several AllWinner A20 board and development platforms available on the market such as Cubieboard2, A20-OLinuXino, IBOX and more. But apart from the team at Free Electrons, few people seem to be working on AllWinner A31, so there are few development platform available, if we exclude consumer products such as tablets and Android TV Boxes. There’s now an AllWinner A31 development board thanks to Mixtile LOFT-Q board, which also comes in LOFT Kit to make a complete mini PC with enclosure.
Mixtile LOFT-Q specifications:
- SoC – Allwinner A31 quad core ARM Cortex-A7 processor with PowerVR SGX544 MP2 GPU
- System Memory – 2GB 64-bit DDR3
- Storage – 8GB eMMC (ver 4.51), SATA III connector for 2.5″ drives, and SD card Slot
- Video Output – HDMI 1.4 up to 1080p
- Audio I/O – HDMI, 1 headphone/TOSLINK composite jack, 2 onboard MIC
- Connectivity – 10/100/1000M Ethernet, WiFi 802.11 a/g/n, Bluetooth 4.0, and Zigbee (
- USB – 4x USB 2.0 host post, 1x micro USB 3.0 device port
- Debugging – UART debug connector, JTAG connector
- Expansion header – 180-pin header with access to I2C, SPI, LCD, MIPI DSI, RGB/LVDS, CSI, MIPI CSI, ADC, CTP, RTP, SPDIF-OUT, SPDIF-IN, GPIO, etc…
- Sensor – Acceleration sensor, IR receiver
- Misc- Battery slot for RTC
- Power – 12V/4A (48W)
The company says the board is running an open source version of U-Boot and the Linux Kernel, the board can decode 4K videos, and support Blu-ray video playback. It can be used as an external USB hard drive when connected via the micro USB 3.0 port. The binary images and source code are not there yet, but they should eventually show up in http://www.mixtile.com/downloads/, as they did with their previous Garage board powered by Exynos 4412. Documentation for the previous board appears to be limited, but they still released the schematics (PDF).
The board will also be available as part of a kit called LOFT Kit adding a tempered glass cover, an aluminum frame and baseplate, 2 silicon rubber pads and a thermal pad, an hard disk holder, a 12V/4A power adapter, and an assembly manual.
