# Connect J-Link EDU Mini to MR-CANHUBK344 with Cognipilot debugger

{% hint style="success" %}
This is an alternative connection using a Cognipilot debugger adapter.
{% endhint %}

First take the J-Link EDU Mini, you can find more information here: [WITB MR-B3RB-BMF](/mr-b3rb/archive/whats-in-the-box-pre-production-version/witb-mr-b3rb-bmf.md#j-link-edu-mini-debugger)<br>

Now, you just need to connectConnect the USB cable to your development computer and also remember to connect power to the Buggy (the LiPo battery to the PDB) in order to flash the MR-CANHUBK344, as the board needs to be connected to the power. Then, you can return here to follow the instructions: .\
