[Updated: Jan. 18, 2017] — The $15 “Pine A64” SBC runs Linux or Android on a quad-core 64-bit Allwinner A64 SoC, and features dual expansion buses, one of which is Pi 2 compatible.

Roll over Raspberry Pi — there’s a new price/performance leader among hacker SBCs, and its name is Pine A64. Fremont, Calif. based startup Pine64 quickly blew past its Kickstarter funding this week, and is rising fast. Yet, there’s plenty of time to get the $15 early bird special for the base-level Pine A64 board, or $19 for the Pine A64+, which doubles the RAM and adds a few more interfaces. The prices stay the same throughout the campaign’s Jan. 23 wrap-up. Early birders benefit only by getting the board earlier, with shipments due from February to April.

The Pine64 runs Ubuntu Linux or Android on a quad-core, 64-bit Allwinner A64 SoC for tablets. At $5 a pop, the 1.2GHz, Cortex-A53 based A64 is even cheaper than the similar Allwinner H64 SoC that recently appeared in the Remix Mini mini-PC. The A64 is mated with a 500MHz, dual-core ARM Mali400-MP2 GPU.

According to Pine64, the Allwinner A64 runs at 11,040 MIPS, or 20-30 percent faster than similarly spec’d 32-bit SoCs. With the help of the A64 and Mali GPU, the Pine A64 can output [email protected] over its HDMI port.

So far, the lowest cost 64-bit open spec SBC we’ve seen to date is Qualcomm’s $75 DragonBoard 410c, based on the quad-core Cortex-A53 Snapdragon 410 SoC. Suddenly, the quad-core, Cortex-A7 based Raspberry Pi 2 ($35) and $9 to $24, single-core Cortex-A8 Chip don’t look quite so extraordinary. Neither does the single-core, ARM11-based Raspberry Pi Zero, which starts at $5, but really requires about $25 for a basic hacker-friendly configuration. Even the $15 Orange Pi PC with its 1.6GHz, quad-core Cortex-A7 is not quite as irresistible as it seemed when it launched in August.

The 127 x 79 x 21mm Pine A64 and Pine A64+ are identical except that the A64+ doubles the RAM to 1GB DDR3, making it “strongly” recommended for Android use. You can also buy a $29 version of the Plus with 2GB RAM.

The Plus model moves from 10/100 Ethernet to 10/100/1000Mbps, and adds a DSI video port in addition to the standard HDMI port. It also adds a touchpanel interface, as well as an optional 7-inch touchscreen. In addition, the Plus provides a CSI camera port with an optional 5-megapixel camera.

Standard features on both versions include dual USB 2.0 ports, and an audio jack with mic input. A microSD slot for up to 256GB is available (one FAQ entry says it actually tops out at 128GB), but the base prices do not include a storage card. The microSD slots are touted for being bootable, letting you quickly reflash the board if it bricks or just as quickly switch operating systems.

Three I/O expansion headers are also provided. One 40-pin interface is called a Pi-2 connector, but there are no claims made here for Raspberry Pi compatibility. There’s also a 34-pin Euler interface. Together these provide the usual serial I/O, as well as SPDIF out, IR receiver, and speaker interfaces (see spec sheet below). A third header implements a 10-pin console interface. In addition to the options listed above, there will be a variety of optional enclosures, keyboards, airmouse, IR remotes, and more available by the ship dates.

The Pine A64 supports a variety of ARM Linux distributions, including OpenWrt, but is optimized for Ubuntu and Android 5.1 “Lollipop.” It also supports the open source OpenHAB IoT stack.

Interestingly for a hacker board, the Pine A64 supports an extended -20 to 70°C temperature range. This, combined with the extensive expansion connectors, OpenHAB connection, and various comments in the videos and Kickstarter copy, suggest the Pine A64 is really aimed at high-end IoT devices as much as the media-centric applications you would expect for a 64-bit board.

The Pine A64 will be based on a combination of open source software and open spec hardware, will be supported with an online store. There are extensive FAQ notes on the Kickstarter page, and Pine64 co-founder TL Lim has sent us pin assignment charts for the expansion connectors (see charts below). Lim co-founded Cloud Media (formerly Syabas Technologies), which makes the Popcorn Hour and Open Hour Gecko media players.

In the coming days, the company will provide “more information such as the Wifi/BT connector definition, LiPo battery port, RTC port, DSI port, CSI port and touch-panel port,” wrote Lim. “The Ethernet chip information and information on 64-bit tool chain and other utilities will also post soon, and certain schematics that don’t involve confidential info will also be released,” Lim adds
