  • Page 48: Thermal Design

    When using SBC-D23 boards, it is necessary to consider carefully the heat generated by the module in the assembled final system, and the scenario of utilization. Until the board is used on a laboratory shelf, on free air, just for software development and system tuning, then a heatsink with integrated fan could be sufficient for board’s cooling.
