Intro To The Proxmark3 RDV4: Part 1 - BT/Battery Module Installation

In this post, we'll go over installing the bluetooth/battery module on a brand new Proxmark3 RDV4. The optional module is a great addition to the proxmark as it will help you run it in standalone mode for a short period of time without connecting to an external power supply. This will greatly increase the covert-ness of the proxmark and allow capturing cards much more easily.

Step 1: Remove the antenna cover and the 6 small screws.

This step isn't technically required but makes the whole process much easier.

Step 2: Use a Spudger or similar tool to pull the top part of the cover off of the proxmark circuit board.

The top cover won't be used after this and should be kept for future use if needed. The BT/battery module will connect into the same holes the cover was in.

Step 3: Gently pull up on the black tab and insert the ribbon connector

Once the ribbon connector is inserted correctly, push down on the black connector (shown below) to lock it in place. Be sure to remove the blue heat sink protective tape before moving to the next step!

Step 4: Fold the BT/battery module on top of the circuit board and press together firmly

Ensure the holes align and snap the module into place. There is no cover for this so if it needs to be more covert, you may want to place some sort of case around the whole proxmark.

Step 5: Connect the antennae, screw in the 6 screws and attach the antennae cover

It's easiest if you align the antennae with the holes and attach one screw on each side.

Charge the BT/battery module and stay tuned for Part 2 of the series, which details how to get the proxmark up and running and updated on a fresh install of Kali Linux. In the meantime, feel free to take a look at our blog to fine other useful articles.
