Now, you just need to connect the USB cable to your development computer and also remember to connect the LiPo battery to the PDB to flash the MR-CANHUBK344, as the board needs to be connected to the power. Then, you can return here to follow the instructions: [CogniPilot: Prepare MR-CANHUBK344 for programming](/mr-b3rb/software/mr-b3rb-software-developer-guide/cognipilot-prepare-mr-canhubk344-for-programming.md#prepare-mr-canhubk344-real-time-vehicle-controller)
