NanoPi S2

The NanoPi S2(S2) is designed and developed by FriendlyElec for professionals, enterprise users, makers and hobbyists. It is a small board with WiFi, Bluetooth and eMMC.
It uses the Samsung Quad Core Cortex-A9 S5P4418 SoC with dynamic frequency scaling up to 1.4GHz. It has 1G DDR3 RAM, 802.11 b/g/n WiFi & Bluetooth 4.0 module. Its in-built power management unit uses the AXP228 chip which supports software shutdown. It takes power over the MicroUSB port. It has video input/output interface, 3.5mm audio jack, USB port and MicroSD card slot, serial debug port and ADC pin-header.
An Android and a Debian images are ready for the NanoPi S2. The Android OS supports HDMI and LCD output.
The NanoPi S2 has various interfaces, ports and GPIOs which are compatible with Raspberry Pi's GPIOs. Its PCB dimension is 40 * 75 mm. The NanoPi S2 works with most of the modules and OS images that are developed for FriendlyElec's S5P4418 based boards.

Note:
  1. SYS_3.3V: 3.3V power output
  2. VDD_5V: 5V power output5V. When the external device’s power is greater than the MicroUSB’s the external device is charging the board otherwise the board powers the external device.The input range is 4.7V ~ 5.6V
  3. All pins are 3.3V, output current is 5mA
  4. GPIO1' pin description is different from that of the NanoPi 2. Here is a comparison table40 pins GPIO comparison table
