A  COM  port  that  can  be  used  to  connect  the  Javelin  Stamp  to  other  computers.  
Alternately, you can attach a null modem adaptor to this COM port and then connect 
the Javelin to peripherals such as serial GPS units, mice, etc.   

 

Linear voltage regulator for prototype circuits. 

 

Small breadboard area for building, testing and prototyping circuits. 

 

A power header (supplied by the liner voltage regulator).  This header can be used to 
supply circuits with power.   

 

A Javelin I/O header to connect your Javelin Stamp I/O pins to your circuit. 

 

COM Port I/O header.  You can use jumper wires to connect Javelin Stamp I/O pins 
to the COM port I/O header.  Then you can write code to communicate with another 
serial device such as a computer or peripheral that’s connected to the COM port.   

 

LED power indicator (labeled PWR). 

 

Reset pushbutton.  Press and release to restart the program from its beginning. 

 

A servo port for connecting and controlling servo motors. 

 
As  mentioned  earlier,  the  circuit  examples  in  this  manual  feature  parts  you  can  find  in  the 
Javelin Stamp Starter Kit.  The parts are listed in Table 1.2.  Table 1.3 lists parts that are also 
recommended but not included in the kit.
