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.
| Part Number | Flash (kB) | SRAM (kB) |
| LM3S3826 | 256 | 32 |
| LM3S3J26 | 128 | 20 |
| LM3S3N26 | 64 | 12 |
| LM3S3W26 | 32 | 8 |
| LM3S3Z26 | 16 | 6 |
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.
The main features of LM3S3x26 are:
