FriendlyARM Mini2440 for OEM buyers. Note: OEM purchase orders for 50 or more units require a 70% deposit. What is the difference between the SDK and the OEM? This is just the Mini2440: None of the SDK material, like Power supply, serial cable, USB device cable, Ethernet cable, JTAG connector and cable not included! Samsung S3C2440 processor with MMU at 405 MHz. 64 MBytes of 32 bit wide RAM. This thing is fantastic. The four biggest chips are the 64 MBytes of RAM and 128 MBytes of Flash ROM. Only 10x10 cm and 1.8 cm thick. The four white sockets on the right of the PCB are power, COM Ports, and LAN. The DB9 is COM0. Notice the onboard Mic in the lower right between two white sockets. NOR/NAND boot switch is bottom right, and power switch is top right.Top edge left to right is LCD and touch screen interface, camera interface, reset switch, and power switch. Left edge top to bottom: GPIO connector, also pot for A/D converter, SD Card socket, USB Device socket. Bottom left to right: 10 pin JTAG connector matches included cable, System Bus connector, NAND/NOR boot switch. Right side top to bottom: Power, DB9 COM 0, RJ-45 Ethernet, USB Master, audio out. The right side connections have corresponding white cable conectors on the PCB for more permanent connections in embedded applications. The Mini2440 cold boots Linux+Qtopia in less than 10 seconds. Software can be loaded with Windows, Linux, by USB or Ethernet, or from an SD Card by using the boot loader and a serial terminal. Size 10x10cm. Weight 2.8 oz, 80 grams.

1 GByte NAND Flash Option

Note: The label that says "USB Host Remote" is incorrect. That connector is interrupts and A/D.

 

Please note: The Mini2440 is NOT like a simple ARM7 with a few K of memory. It is a minicomputer system on a chip. That means plenty of RAM and ROM (Flash) to run a multitasking OS with a full GUI. Multiple users can log in if you run Linux and set it up that way. The MMU allows very sophisticated approaches, or it can be ignored and a single dedicated real-time program can be run. Computers with considerably less speed and memory routinely handled 32 to 64 users simultaneously in the past.

If you want to roll your own, will it be easy to generate the OS and tool chain? No, even if you are a Linux expert it will take some effort. Do you have to generate the OS yourself? No. Binaries and sources are provided and the board comes loaded with Linux and Qtopia. Is it easy to write applications with the provided OS and tools? Yes! Use C or C++ and the included gcc ARM compiler and libs. All the I/O is supported with drivers and addresses listed for poking bits around yourself. Once your development is set up in your favorite way, say with Eclipse, it is like any other system. QEMU for the ARM can be used to emulate the Mini2440 and work even faster -- no downloads, just run.

The inner mounting holes fit the Toppoly, Sony, or NEC 3.5" LCD found on the Mini35.
