Development board for the LPC210x line of processors (1/2/3 are all pin compatible) Uses the 20 pin JTAG connector. Has separate headers for SPI and I2C outputs, all other output pins to a single header. Built-in voltage regulator for input from 5v to 12v (max 18v), outputs needed 3.3v and 1.8v for the processor with 3.3v also being fed to header.
