Javelin Stamp module for Java(TM)

The
Javelin Stamp module is a 24-pin DIP module programmed in a subset of the Sun
Microsystems Java language. Java is a trademark of Sun Microsystems, Inc.

Java programming language is not the only thing that makes the Javelin Stamp
module uniquely different from BASIC Stamp microcontrollers:

• 32 k bytes of RAM/program space (leftover space
  can be used for variables, arrays, and serial buffers
• 32 k bytes of non-volatile EEPROM
• Buffered serial communication in the background
• Up to seven UART objects that can communicated
  independently of each other and the main program
• Pulse width modulation in the background
• 8000 instructions/second execution speed (not
  including background processes which run independently of foreground tasks)
