FriendlyARM released NanoPi board this summer, a small and inexpensive development board based on Samsung S3C2451 ARM9 processor with both WiFi and Bluetooth connectivity. The company has now unveils a more powerful, and slightly wider, version with NanoPi2 featuring Samsung S5P4418 quad core Cortex A9 processor with 1GB RAM, AP6212 wireless module, a new HDMI output, and the same connectors for I/Os and LCD displays.
- SoC – Samsung S5P4418 quad core Cortex A9 processor @ up to 1.4GHz
- System Memory – 1GB 32bit DDR3
- Storage – 2 x Micro SD Slot
- Connectivity – 802.11 b/g/n WiFi and Bluetooth LE 4.0 via AP6212 module
- Video Output / Display I/F- 1x HDMI 1.4a, 0.5 mm pitch SMT FPC seat for type-A full-color LCD (RGB: 8-8-8)
- Camera – 24-pin DVP interface
- USB – 1x USB Host port; 1x micro USB 2.0 OTG port for power and data
- Expansions Headers – 40-pin Raspberry Pi compatible header with UART, I2C, SPI, GPIOs…
- Debugging – 4-pin header for serial console
- Misc – User and reset buttons, power and user LEDs, RTC battery header
- Power Supply – 5V/2A via micro USB port
- Dimension: 75 x 40 mm (6-layer PCB)
- Weight – 22 g
The board boots from a micro SD card (on the right below) with either Android 4.4.2 or Debian.
NanoPi2 Wiki describes the board, shows how to install the images, build U-boot, Linux 3.4.x and Android, and provides links to the schematics and mechanical files (PDF). The Debian Image Build System (DIBS) and other tools can also be found on ARMWorks github account.
Unfortunately, I could not find the datasheet for S5P4418 processor [Update: here’s S5P4418 user’s manual], but one Chinese company mentions it’s an upgraded version of Exynos 4412, and I’ve passed their comparison table through Google Translate.
|I/O Voltage Levels|
No level conversion needed
Meets more requirements
4x dual channel DDR3
Easier wiring and impedance control
Needs an external PHY
Eliminate the need for external chip
Supports LVDS directly without an external chip
Some I/Os support interrupts
All I/Os support interrutps
Requires DM9000, which costs more (12RMB ~ $1.9)
Built-in Gigabit Ethernet, and you can use a 3RMB (~50 cents) chip to support 10/100/1000M Ethernet
NanoPi2 board sells for $32, and you can also purchase a kit with a 7″ resistive LCD for $65. Alternatively, 4.3″ and 7″ can be purchased separately for $25 and $35. Sadly shipping is monstrous, as I was asked for respectively $32 and $65 extra for shipping and handling for the board only and 7″ LCD kit with NanoPi2 board. Both match exactly the costs of the board and kit, so hopefully it’s a temporary mistake.
