In this article we will see how to disassemble Pogoplug V4 and attach serial cable to the serial pads on the board.
To begin disassembly we need to remove the two rubber pads on the bottom towards the rear edge. (see white arrows in the image below.) The rubber pads are glued and can be easily removed and replaced.
After removing the two rubber pads we can see the two screws as in the image below.
After removing the screws, we can remove the top cover of Pogoplug and see the main board as in the image below. We just need to be careful about the soft locks (white arrows in the image below) in the front and sides of the Pogoplug.
The pads of the serial connection are shown in the image above:
- GND: Ground Terminal
- Rx: Serial Receive (data into Pogoplug)
- Tx: Serial Transmit (data from Pogoplug)
I used Nokia CA-42 serial cable and identified its terminals as shown in the link below:

Now you can solder your serial cable the way you wish. Continue reading if you are interested to know the way I used myself.
I’ve tried to connect the serial cable and get it from the bottom of the Pogoplug to be able to assemble it again. I ended up with the setup shown below:
I’ve cut the CA-42 cable and attached a connector as shown below. So that I can plug it into this Pogoplug, or use it in another project without re-soldering.
To solder the serial connector to the Pogoplug board, I had to solder it on the bottom side, so that I can extract the wires from the bottom cover of the Pogoplug as shown earlier. The image below shows the bottom side of the board and highlights and serial pads we need to solder. We need to remove the four small screws that fix the board before we can remove it to solder on the bottom side.
The image below shows the 3-terminal wire soldered into the board.
We better use a glue gun to fix the wires into the board to avoid breaking the solder while we extract the wires from the opening on the bottom side of the Pogoplug case. After we extract the wires and fix the board in place, we get something as shown in the image below.
Now we can assemble the Pogoplug again, and connect the serial cable using the external connector as below.
