Disassemble the stick by releasing the metal tabs that hold the cover in place.

Once you have removed the metal casing, you are left with the half-naked stick (note that the release mechanism also comes off easily and then you don't know how to put it back together, so take a photo and memorise the positioning well). 4. Before shorting the stick, connect the previously soldered cables and molex to the USB serial (photo immediately below) and to the stick (the molex, of course) and check that the jumper on the usb key is set to 3.3V {% include image.html file="ma5671a-root-8.jpg" alt="TTL" caption="TTL" %} +{:style="counter-reset:none"} 5. The disassembled stick will appear as in the photo, in which I have highlighted in red the 2 pins to be shorted. Here they use wire, but a pair of tweezers is sufficient (I used those, in fact).
