Cygni is a general purpose development board based on LM3S3N26 from Texas Instruments. This is a Cortex M3 ARM microcontroller running at 50 MHz with 64 KB of Flash and 12 KB of SRAM.
Cygni includes two 19 pin (male) row headers for the main I/O, however these are not soldered to the board. This allows you to choose upward mounting for pin-pin or daughter board style development, or downward facing for breadboard development (using two breadboards). Female headers could also be used if desired although they are not supplied.
