Assembly Instructions
Note: On all of our PC boards for PICAXE(R) processors, the 2x5 header at the top edge of the board and the row of header pins along the bottom edge of the board are inserted from the bottom of the board and soldered on the top of the board. In other words, the black plastic piece that connects the pins is below the board. It is best to leave these headers to last.
To assemble the SIP-08 project board, it is best to proceed from the smallest to the largest parts: solder in the diode first (make sure the cathode is toward the right, as indicated on the silk-screen), then the four resistors, followed by the capacitor and the switch, then the IC socket, then the 3-pin header directly above the IC socket, and finally the LED (be sure to insert the cathode lead into the square pad on the board).
When you have soldered all the parts that mount on the top of the board (and solder on the bottom), make sure all the excess leads have been clipped. At this point you may want to rub the bottom of the board a few times on a piece of emery-type sand paper to remove any sharp edges. You can use flux remover to clean the bottom of the board, but I have found that ordinary paint thinner and a tooth brush works just as well for this purpose, and it's easier on your hands. The following photo shows the results of sanding and cleaning the bottom of the board. (The photo is actually of a Prog-05 board, but the principle is the same.)

Now you are ready to insert and solder the 2x5 header at the top of the board, and the 8-pin header at the bottom of the board. As mentioned above, each of these headers is inserted from the bottom of the board, and soldered on the top of the board.
In order to simplify this step, it's helpful to first insert the longer ends of the 2x5 header into one breadboard (near its edge), and the longer ends of the 8-pin header into another breadboard (near its edge), and suspend the SIP-08 board between the two breadboards (see the photo below). You can't use one breadboard for this purpose, because the spacing of the top and bottom headers doesn't match that of a breadboard. Notice that the power rail has been removed from the breadboard on the left - this is necessary to enable the SIP-08 to span the breadboards properly. (Also notice that the headers are already soldered in the photo, This is because I forgot to take the photo before doing so - but you get the idea anyway!) Once you have the SIP-08 board properly spanning the breadboards, solder all the header pins on the top of the SIP-08 board.

In order to connect the SIP-08 project board (or any of our PICAXE-related boards) to your PC, you will need to construct a suitable programming cable - just follow the detailed instructions presented here.
The two photos below demonstrate how to install the SIP-08 project board on a breadboard. Notice that the silk-screen labels identify the PICAXE I/O pin connections. In the second photo, the SIP-08 has been removed to reveal how the power and ground connections are made underneath the board.

No additional circuitry is necessary to test the SIP-08 board - just write a program to blink the on-board LED (on output0) and download it to the board. Be sure the shorting jumper is installed on the two pins to the right of the 3-pin header, or the LED won't light!
