Mini2451 Single board Feature

The Mini2451 has 4 UARTS so there are now 4 UART headers and the 5th white header is the OEM power supply same as the Mini2440. Notice also that the big 3-pin regulator packages are gone. Instead there are 5 very small efficient  DC/DC converters spread around the board to be closest to where they are needed. They supply the 3.3 and 1.8 volts and derive it from the main 5V input. There is also no voltage selection jumper for the LCD connector. The rest of the headers match up to the Mini2440 where possible. The connectors and SD socket are all in the same place. The Mini2451 USB Device is the more modern MiniUSB style and is the same place as the USB Device on the Mini2440.

In the few years since the Mini2440 was introduced, the change in manufacturing is striking. Notice how parts have shrunk, the smaller size of discrete components and the big increase in the number of discretes that can fit. These allow pull-ups, pull-downs, biasing, line drivers, impedence matching, and all kinds of good things. Notice also the round gold spots. These are for "bed of nails" test fixtures or things like JTAG to program NAND in a fixture without connecting cables.

The Mini2451 has a Superboot bootloader version to program NAND from an SD card. This is great for production since PC's are not needed for programing and you can do a bunch of boards at a time.
