Tiny, open spec SBC offers wireless and 8GB eMMC

Oct 28, 2016 — by Eric Brown 3,483 views

[Updated: 9:30PM] — FriendlyElec’s $45, 75 x 40mm “NanoPi S2” SBC runs Debian or Android on a quad-core A9 SoC, and offers RPi expansion, WiFi, Bluetooth, and 8GB eMMC.

FriendlyARM, which is now selling its hacker boards under the name FriendlyElec, is one of the most prolific of hacker board makers. The Chinese firm spins numerous variations on its open-spec, Allwinner or Samsung based “NanoPi” single-board computer line, five of which made it into our recent Hacker Boards SBC survey. The company even builds boards for other projects, as it did with LinkSprite’s latest NanoPi M1-based pcDuino4 Nano. FriendlyElec’s latest NanoPi S2 SBC adds to its line of Samsung S5P4418 based boards, including the NanoPi2 Fire, NanoPC-T2, and NanoPi-M2.

The $45 NanoPi S2 most closely resembles the $23 NanoPi2 Fire, sharing the same 75 x 40mm footprint and similarly running Debian Linux or Android on the quad-core, Cortex-A9 S5P4418 SoC clocked to 1.4GHz. Other common features include USB 2.0 host, micro-USB, microSD, 45-pin LCD interface, camera link, and AXP228 power management chip. The two boards also share in common their Raspberry Pi compatible 40-pin connectors.

The NanoPi S2 dispenses with the Fire’s GbE port, but adds WiFi and Bluetooth. It also shrinks the HDMI port to mini-HDMI. The DDR3 RAM count stands at 1GB, split into two 512MB banks. New features on the S2 include 8GB of eMMC, an ADC pin header, an audio jack, and an LVDS interface.

    By “common features” you don’t mean “also on the NanoPi2 Fire” right ? Couldn’t find any mention of wifi nor bluetooth on FA’s NP2 Fire webpage.

  2. ricky siah says:

    FriendlyARM is offering a good deal for those embedded PC, but however most of them do not offer “complete part” or “missing components”, for example LCD interface, ethernet port, eMMC, etc… What assume.

  3. Jerry says:

    So what’s the supported kernel?
