The ARM9 Family has several members.  The NanoPi, Mini2440, Micro2440, Mini2451, Micro2451, an Tiny2416.

NanoPi is a low power consumption, Samsung S3C2451 based ARM SOC that FriendlyARM developed for Linux developers, hobby makers and hobbyists.  its size is only half of the Raspberry Pi (RPi) and its GPIO pin is compatible with the RPi's.  The NanoPi integrates both the WiFi and Bluetooth 4.0, and has MiPi sockets for cameras and LCDs.  It is easy to run and install Linux/Debian from a TF card.  These features make it a good platform for applications in IOT, unmanned vehicles, drones and intelligent devices.

The Mini2440 405 MHz ARM9 Family has several members. The Mini2440 is a 10x10cm PCB with the Samsung S3C2440A SOC (System On Chip) with two kinds of Flash, NAND and NOR, 64 MBytes of RAM, and all the peripheral I/O. Please see the Mini2440-SDK page for details.

There are versions with 3.5, 4.3, 5.0, and 7" LCDs, and a VGA adapter for 1024x768. Basic systems have 128 MBytes of NAND Flash. This is enough for 95 percent of applications. There is a NAND option for 1024 MByte (1GByte) and this is becoming more popular. Up to 32 GBytes of Flash can fit the SD Card socket. We use a simple (?) naming scheme.

Micro2451 - Fits Micro2440-SDK


Mini2440 is the PCB with processor.

Mini2440-35 is the Mini2440 + 3.5" LCD. The LCD module is the same width as the Mini2440 and easily mounts on the board.

Mini2440-A70 is the Mini2440 + 7" LCD

SDK is the System Developer's Kit of serial, USB, and Ethernet cables and a power supply and DVD. The NAND option is not a separate item. It designates which version of the Mini2440 to ship.

OEM is a Mini2440 variant with no SDK. OEM is Original Equipment Manufacturer, and these boards are usually bought for use in an embedded product. You can save weight and money if you combine SDK and OEM versions. For example, if you need to make 10 devices and have two people doing development you could get 2 SDK and 8 OEM, provided you will not need the PSU and cables in the final product. Note that we do not recommend the SDK PSU for commercial use. It is a simple supply suitable for the lab and development. For better fusing and full certificatons, see the German PSU under the Accessories listings.

Mini2440-35 is a Mini2440 with a 3.5" LCD. The display is 240x320 with an integrated touch pad. This is a very nice high contrast LCD that can mount to the Mini2440. It is shipped mounted on brass standoffs.

The Mini2440-VGA is a Mini2440 with a VGA adapter PCB that mounts like the LCD. 


The Micro2440 is like a "Stamp" or Core Module for the Samsung S3C2440A 405 MHz ARM9 System-On-CHip. The small PCB contains the processor, 64 MBytes of SDRAM, NAND and Nor Flash, and all the I/O broken out to 2mm pin headers. The standard Micro2440 has 128 MBytes of NAND. There are options for 256 MBytes and 1024 MBytes and LCD displays.The LCDs have about a 12 inch cable folded underneath for remote mounting. Custom cables are available.

Micro2440SDK  For development, there is the Micro2440-SDK which provides power regulation, connectors or I/O and any needed hardware like the Ethernet adapter. This has all the features of the Mini2440 + a USB hub that allows the 4 USB host sockets. The SDK includes what you see here, plus the power supply, Ethernet cross-over, serial, USB, and JTAG adapter cables with DVD. Please see the Micro2440SDK page for details
