Raspberry Pi Zero has two noticeable attributes compared to other Raspberry Pi boards: it’s smaller and it’s cheaper. FriendlyARM has now designed another model for their NanoPi family, that about 12% smaller, although not quite as thin at all due to its Ethernet jack and USB connector, and much faster than Raspberry Pi Zero, with NanoPi NEO board powered by Allwinner H3 quad core processor.
- SoC – Allwinner H3 quad core Cortex A7 @ 1.2 GHz with an ARM Mali-400MP2 GPU up to 600 MHz
- System Memory – 256 or 512 MB DDR3
- Storage – micro SD card slot
- Connectivity – 10/100M Ethernet
- USB – 1x USB 2.0 host ports, 1x micro USB OTG port, 2x USB via headers
- Expansion headers
- 24-pin header with I2C, 2x UART, SPI, PWM, and power signals
- 12-pin header with 2x USB, IR pin, microphone and Line OUT signals
- Debugging – 4-pin header for serial console
- Misc – Power and status LEDs
- Power Supply – 5V/2A via micro USB port or VDD pin on headers.
- Dimensions – 40 x 40 mm (Raspberry Pi Zero: 65mm × 30mm)
There aren’t any interfaces to connect an external display, so the board can only be used for headless applications. In case you need that board with low profile, you could probably unsolder the Ethernet jack and USB port, or if you buy in quantities, maybe the company could remove those for you.
The Wiki is still in construction, and for now only in Chinese, but we can find out that FriendlyARM provides Ubuntu-Core with Qt-Embedded for the board relying on Linux 3.4 legacy kernel. However, Allwinner H3 should get full mainline support in Linux 4.7 or 4.8, so I’m fully expecting the board to be supported in mainline kernel in a few months. The schematics (PDF), and header pin assignments are also available in the wiki.
NanoPi NEO is not yet for sale, but considering the larger NanoPi M1 board with the same processor sells for $11 + $5 shipping, I’d expect the new board to go for around $7 + $4 or $5 shipping, about the same price as I paid for Raspberry Pi Zero.
NanoPi NEO sells for $7.99 with 256 RAM, $9.99 with 512 RAM + shipping ($4 to my location).
