8. I/O Pin Access Header (X2): The BASIC Stamp module's 16 I/O pins, labeled 0 to 15, are
connected to this header. Its location adjacent to the breadboard makes it convenient for
connecting circuits to I/O pins. Keep in mind that I/O pin access is also brought to the X4, X5,
and X1 headers, so be careful not to build conflicting breadboard circuits if you are using these
other headers as well.
9. AppMod header (X1): The AppMod header provides power, I/O pins, Vdd, Vin, and Vss access
for any devices that are designed to use this 2x10 socket. Examples include the LCD Terminal
AppMod (#29121), CMUcam (#30051), Easy Bluetooth Module (#30085), and Say It voice
recognition module (#30080).
10. Reset Button: The reset button can be used to restart your BASIC Stamp without having to
cycle the power. This saves wear-and-tear on the power switch for simple program restarts.
Some advanced programming techniques use the reset button and the BASIC Stamp EEPROM
program and data storage as a way to toggle between different program functions.
11. 3-Position Power Switch: The leftmost position (0) is OFF – all power is disconnected. Always
place the switch in this position when adding or changing components on the breadboard. The
middle position (1) provides Vin (unregulated battery or power supply voltage) to the regulator,
the BASIC Stamp socket, and to the connectors marked “Vin.” This switch position also makes
Vdd (5 volts) available to Vdd sockets on the breadboard and AppMod connectors. The rightmost
position (2) also provides power to the servo connectors X4 and X5. Especially if your program
causes a robot with servos connected to X4/X5 to start moving immediately, you can keep the 3-
position switch in position (1) while loading the program, then switch to position (2) when you
are ready for the robot to start moving.
12. Socket for BASIC Stamp: This socket is compatible with all 24-pin BASIC Stamp modules. It
connects the BASIC Stamp to the programming connector, power, the power indicator LED, reset
button, and all I/O pin headers.
13. Serial Programming Connector: This is a female DB9 socket for programming and for two-
way serial communication between the BASIC Stamp and your computer. You can connect
directly to a serial port on your computer, or use a USB to Serial Adapter to connect to a
USB port.
