UPA-4x4 Assembly Instructions
Use the following photo as a reference as you assemble the UPA-4x4 Universal Programming Adapter.

Parts List (All parts are available at JRHackett.net.)
| Label | Description |
| D1 | Diode, BAT85 | R1 | Resister, 10k, 1/6 Watt |
| R2 | Resister, 22k, 1/4 Watt |
| R3 | Resister, 180 ohm, 1/4 Watt |
| None | Header, Male, 2x5 |
| None | Header, Male, Snap (4 or 8 pins) |
Note: On the UPA-4x4 Universal Programming Adapter, the short ends of the 2x5 male header and the 4-pin male header(s) 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. Do not solder these header(s) until all other parts have been soldered in place.
To assemble the UPA-4x4, it is best to proceed from the smallest to the largest parts. The order of the parts in the parts list is arranged this way, so just work your way from the top of the parts list to the bottom. The BAT85 diode is polarized; make sure it is inserted in the proper orientation before soldering. Also, be sure to use a 1/6 Watt 10k resistor - a 1/4 Watt resistor won't fit properly.
When you have soldered the four parts that mount on the top of the board and are soldered on the bottom, make sure all the excess leads have been clipped from the bottom of the board. At this point you may want to rub the bottom of the board a few times on a piece of emery-type sandpaper 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 actually shows the bottom of a Prog-05 board, but the principle is the same.)

Now you are ready to insert and solder the 2x5 male header and the 4-pin (single-row) male header(s). As mentioned above, the short ends of each of these headers is inserted from the bottom of the board and soldered on the top of the board. Decide which configuration you want (see the top photo), and insert one or two 4-pin male headers accordingly. In order to simplify this step, it's helpful to first insert the longer ends of each header into a breadboard (appropriately spaced) and then mount the UPA-4x4 on the short ends of the headers and solder all the header pins on the top of the UPA-4x4.
In order to connect the UPA-4x4 (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.
