Use the Micro2440-SDK as a development platform for custom designs that will use the Micro2440-OEM "stamp". Or use it as is for projects that need the I/O. 4 USB Host connectors and 1 USB Device (slave). Three DB9 RS232 serial lines and connectors to the same ports in TTL. A CMOS camera port and GPIO with 10 bit A/Ds and all the goodies you would expect -- SPI, I2C, PWM, timers and counters, etc. Same as the Mini2440 spec and software compatible. The Mini2440 Cable Kit fits this unit as well. Note: The Micro2440 is included with the SDK.
