Page 40: Thermal Design
When using ASTRID 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.
