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.

The 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).
• The Javelin Stamp module is compatible with any BASIC Stamp programming board with a 24 pin DIP socket.  The Javelin Stamp works with all of the power supplies that we carry in stock.
